Q3 Filing systemq


Qcommandsq


									

HADFS provides a variety of commands used to access HADFS disks. The
following pages describe these commands. They are all B*b commands, and so
must be at the end of a program line, or accessed using OSCLI from BASIC. 
Some of the commands are provided by HADFS as filing system commands, some
of them are provided by HADFS as general utility commands, and some are
provided by the MOS, which communicates with the HADFS filing system to
implement them. There are also some commands that are in DFS on BBC Bs and
in the MOS in Masters. There are also transient commands which are loaded
from disk to run them. The commands are labelled as EFilinge, EUtilitye, EMOSe,
ETransiente or EDFS/MOSe. All HADFS commands can be prefixed with BHb to prevent
clashes. Commands can be prefixed with B\b to pass it to the filing system
only, as with SJ Fileservers. HADFS commands can be terminated by any
non-letter, so B*DIR $b is the same as B*DIR$b, but B*DIR FREDb cannot be
shorted to B*DIRFREDb, this would look for a command file IDIRFREDi.


DCommand Syntaxd

The syntax abbeviations used in these descriptions, and in B*HELPb messages,
are as follows:

	<afsp>	ambiguous file. A filename or directory name that can
		include the wildcard characters B#b and B*b.
	<fsp>	file specifier. A filename or directory name that does not
		include the wildcard characters B#b and B*b.
	<src>	source filename/dirname/drive.
	<dest>	destination filename/dirname/drive.
	<dir>	a directory.
	<user>	a user number.
	<drv>	a drive number.

If a syntax abbreviation appears in brackets, this indicates that it is
optional.


DFilenames and pathnamesd

Filenames can consist of one to ten alphanumeric characters, containing no
spaces, and none of the following special characters which are reserved
and cannot be used in filenames: B"b, B#b, B$b, B&b, B^b, B:b, B*b, B.b and B@b.

Pathnames consist of one or more filenames separated by B.b, optionally
including the following absolute directory reference characters:

	B$b	root directory, and disk prefix. Identical to B:b.
	B:b	root directory, and disk prefix. Identical to B$b.
	B%b	library directory (LIB). A filename can also contain B%b.
	B&b	user root directory (URD).
	B@b	currently selected directory (CSD).
	B^b	parent directory.

So the pathname B%.FREDDYb refers to the file IFREDDYi in the library
directory, and B:1.HELLOb or B$1.HELLOb refers to the file IHELLOi in the root
directory of drive 1. The B$b and B:b can be used interchangably. The B%b
character on its own refers to the Library, otherwise it can be used as
any other character, for instance B%PrintQb.

The following wildcard characters are used:

	B#b	matches any one character
	B*b	maches any characters


D*/<afsp> (<parameters>)					MOSd

B*/b is an abbreviation for B*RUNb except that B*RUNb only checks the current
directory and B*/b checks the current directory and the library directory as
with unrecognised B*bcommands. It is normally used to prefix a command to
prevent a ROM version being used and force a disk-based version to be
used.


D*\<command> (<parameters>)					MOSd

If a command is prefixed with B\b it is checked against HADFS's filing
system commands and is not passed on to the filing system. They will not
be searched for on the disk or passed to other ROMs if they are not
matched. This is the same as with SJ Fileservers.


D*|<comment>						MOSd

A command starting with B|b is a comment and is entirely ignored.


D*ACCESS <afsp> <access>					Filingd

This command changes the access string on a file, eg

	B*ACCESS MATHS WR/Rb

Each letter in the access string refers to a different type of access
allowed to the file: 

	BLb - Locked  => The file cannot be deleted or overwritten or renamed.
	BWb - Write   => The file can be written to using random access.
	BRb - Read    => The file can be read with LOAD or random access and
			can be executed with B*b, B*/b or B*RUNb.
	BPb - Private => The file cannot be seen by non-owners.
	BEb - Execute => The file can be executed with B*b, B*/b or B*RUNb. If
			there is no Read option, then the file can only be
			executed, and is a run-only file.

The B/b character separates the owner's access (on the left) from the public
access (on the right). You are the owner of a file if you own the
directory that it is in. When a disk is B*INSTALLbed or B*FORMbatted, you own
the whole disk. Ownership is changed using the B*ACCOUNTb command, and
allows you to segregate files and simulate an network server environment
using local disk drives. Saving a file on top of an existing file does not
change the file's access setting.


D*ACCOUNT <afsp> <acc> (<aux>)					Filingd

This sets the hexadecimal main and auxilary account numbers of a
directory. The auxilary account number is specified in brackets, eg
B*ACCOUNT $ 0 (0)b. Account numbers are 12-bit numbers, so can be 0 to FFF.
When a disk is B*MOUNTbed, your account number is reset to 0, so to own any
objects in directories that have had the account number changed, you must
log into them using B*I AMb.


D*BACKUP <src> <dest>						Programd

B*BACKUPb makes an identical copy of a disk. It is implemented as a
transient program and is described in Chapter 5.


D*BUILD <fsp>							DFS/MOSd

B*BUILDb opens a new file with the specified name and all subsequent lines
of keyboard input are directed to the file. Input is terminated by
pressing Escape.


D*BYE								Filingd

This closes any open files and dismounts all the disks. You should always
use this (or B*MOUNTb) before changing a disk.


D*CAT (<dir>)							MOSd

The B*CATb command provides a list (catalogue) of the files in the selected
directory. The files are currently not listed in alphabetical order, but
it is intended that they will be in the future. The top three lines
contain information about the directory being catalogued. With the example
below, the first line shows that the directory being catalogued is called
BPROGRAMSb and the disk it is on is called BMyDiskOneb. The CSD is the root
(B$b) and the library directory is called BLibraryb.

B	PROGRAMS   (33)     Owner 000
	MyDiskOne           Option 0 (Off)
	Dir. $              Lib. Library

	MATHS      WR/R     GAMES      DL/
	STARTUP    LR/R     START2     R/Eb


D*CDIR <dir>							Filingd

This command creates a subdirectory. If the specified subdirectory already
exists, then the command returns with no errors. If a file already exists
with the same name then a BFile existsb error will be generated. The created
directory has its access locked.


D*CLOSE								MOS/Utild

This closes all open files and ensures any data in buffers is written to
disk. It is identical to using BCLOSE#0b from BASIC.


D*COMPACT (<drv>)						Programd

This compacts a disk creating larger areas of free space. It is
implemented as a transient program and is described in Chapter 5.


D*COPY <src> <dest>						Filing/Transientd

On the Master series, this command is implemented in the ROM using the MOS
B*MOVEb command. On the BBC it is run from disk as a library command. It
copies a specified file, creating another copy, leaving the original
intact, eg:

	B*COPY Prog1 $.Fred.OldProg1b

The B*MOVEb-based version uses only the private MOS memory, including any
unused shadow screen memory, so the user program area is untouched. The
disk-based version uses the HADFS buffers and the CFS buffers at &900 to
&AFF in the I/O processor, so again the user program area is untouched.
For copying multiple files and to other filing systems, use the transient
program ITreeCopyi instead. See Chapter 5.


D*DELETE <fsp>							Filingd

This simply deletes an entry from the directory, eg:

	B*DELETE FREDb

If the file is locked, the error BFile lockedb is generated. If you try to
delete a directory that has entries in it, the error BDir. not emptyb is
generated. You can only delete files in directories that you own.


D*DIR (<dir>)							Filingd

This command allows you to move between directories, eg:

	B*DIR PROGRAMSb

The example selects IPROGRAMSi to be the Currently Selected Directory (CSD).
Doing B*DIRb with no name will reset the CSD to the User Root Directory
(URD), this usually being B$b, or the directory selected with B*I AMb. The CSD
can be refered to in pathnames with B@b, eg: 

	B*RUN @.FREDb

This would run the file IFREDi in the CSD.


D*DISABLE <option>							Transientd

The B*DISABLEb command allows various features to be disabled.

B*DISABLE HADFSb disables HADFS in the same was as B*FX90,6,1b.

B*DISABLE DFSb disables the DFS filing system, while leaving the OSWORD &7F
call available. This will usually drop PAGE by &200.

B*DISABLEb is reversed with B*ENABLEb.

After using B*DISABLEb Ctrl-Break has to be pressed.


D*DISKS								Transientd

This command lists the names of all the disks present in all the available
drives, and the amount of free space on them. A typical display would be:

B		>*Disks
		Drv Title              Free   Used
		:0 Documentation         1K   399K
		:1 HADFSSystem          22K   378K
		:4 IDEDRIVE4         32686K    82K
		:I InternalFiles         0K    28Kb


D*DUMP <afsp>							DFS/MOSd

This command displays a hexadecimal and ASCII dump of the named file, with
eight bytes per line, preceeded by the displacement from the start of the
file. Non-printable characters are displayed as a B.b character.


D*ENABLE (<option>)						Filingd

This command is used without a parameter to enable the dangerous commands
B*FORMb and B*INSTALLb with the B$b parameter. With a parameter it is a
transient program used to reverse the functions disabled with B*DISABLEb.

It should be given before the command is used, eg:

	B*ENABLE
	*FORM160 0b

If a command is not enabled, then you are asked BGo? (Y/N)b and a keypress
is waited for. Pressing anything other than BYb or Byb will result in the
command being abandoned, and a BNot Enabledb error being generated.

B*ENABLE HADFSb enables HADFS in the same was as B*FX90,6b.

B*ENABLE DFSb enables the DFS filing system after being disabled with
B*DISABLE DFSb.

After using B*ENABLEb with a parameter, Ctrl-Break has to be pressed.


D*EX (<dir>)							Filing/MOSd

This command is similar to doing a B*INFOb on all the files in the
directory. If no directory is given, the CSD is listed. An example would
be:
	B>*EX
	$          (69)     Owner 000
	MyDiskOne           Option 0 (Off)      Dir. $              Lib. $

	!ReadMe    67542742 26533684   002DAD   WR/R       08/10/1989 00004A
	Manual1    65524372 38573523   001029   WR/R       08/10/1989 000078
	COMPACT    FFFF1900 FFFF8023   00055E   LWR/R      17/10/1989 0000A2
	COPYFILES  FFFF1900 FFFF8023   000652   LWR/       18/10/1989 0000A8b


D*EXEC (<afsp>)							MOSd

This command reads the specified file in byte by byte as if it were being
typed in at the keyboard. This is usually used with B*OPT4,3b to B*EXECb a
!Boot file. If a file's execution address is &FFFFFFFF or the load address
if &FFFFFFxx, then attempting to do B*RUN <afsp>b will do B*EXEC <afsp>b
instead. B*EXECb without a filename closes any open B*EXECb file.


D*FILES								Utild

B*Filesb lists the information on all the currently open files. The display
shows each channel's object information, sector start, current pointer,
extent, directory sector, disk ID number and allocated space. The object
information will be either *CLOSED* or start IN, OT or UP for OPENIN,
OPENOUT or OPENUP. The next six bits are the EOF flag, Directory, Write
attribute, Read attribute, Output buffer modified, Input buffer present.
An example display would be:

B>*Files
25 OT..WROI 00:0004E5 PTR=0000002A EXT=00000037 Dir:00004A ID:D951 Alloc=000040
26 IN.D.... 01:000047 PTR=00000000 EXT=00000300 Dir:000047 ID:F01D Alloc=000003
27 UPE.WROI 00:000285 PTR=0000023B EXT=0000023B Dir:0000D3 ID:D951 Alloc=000003
28 *CLOSED* 00:000000 PTR=00000000 EXT=00000000 Dir:000000 ID:0000 Alloc=000000
29 *CLOSED* 00:000000 PTR=00000000 EXT=00000000 Dir:000000 ID:0000 Alloc=000000b


D*FORMnn <drv>							Utild

This command, which needs to be B*ENABLEdb, will format a disk in drive 0 or
1. The number of tracks is specified by nn, this can be from 1 to 255,
though sensible values would be 40, 80 and 160. The formatted disk is a
blank data disk with the title B(Untitled)b. The command can be used without
HADFS selected, and if so, the drive parameter can be 0 to 3 which will
create a blank DFS disk. As an example,

	B*FORM160 0b

will format a double-sided 80 track disk. Many disks and disk drives can
actually access about 82 tracks, so you could use 

	B*FORM164 0b

to format a double-sided 82 track disk.


D*FREE (<drv>)							Filingd

This displays the free space available on the disk, or the disk the CSD is
on if no drive is given. An example would be:

	B>*FREE
	000193 Sectors     103,168 bytes free
	0004AD Sectors     306,432 bytes usedb


D*HADFS								Utild

This command selects the HADFS. Once selected, HADFS becomes the current
filing system and all filing operations are directed to it. HADFS can also
be used as a temporary filing system using the prefix B-HADFS-b.


D*HELP <keyword>						MOSd

Displays list of helpful information. HADFS responds to B*HELP HADFSb to
list the HADFS Filing commands and B*HELP UTILSb to list the HADFS utility
commands.


D*I AM <dir>							Filingd

This command is used to log on to a specified directory on a disk. An
example would be:

	B*I AM PROGRAMSb

which would set the User Root Directory and the CSD to I$.PROGRAMSi on the
default user drive, normally drive 0. A directory I$.Libraryi is looked for
on the default library drive and the logged on drive if different, and if
found, the library directory is set to it. The autostart command is then
executed (see B*OPT 4b). A drive other than the default user drive may be
logged on by prefixing with a drive identifier, and subdirectories can be
logged on to, eg:

	B*I AM :1.WORK.SHEETSb

would log into the directory IWORK.SHEETSi on drive 1, and look for a
library directory on drive 1 and then the default library drive. If the
specified directory cannot be found, then B$b on the default user drive is
logged into instead.


D*INFO <asfp>							Filingd

This displays the file information for a particular file, eg:

	B*INFO MATHSb

produces a string of information about the file IMATHSi. The format is:

<name> <load address> <execution address> <size> <access> <date - dd/mm/yyyy>
<system internal name>

For example, the above command may produce the following output:

B	MATHS      FFFF1900 FFFF8023  000734   WR/R       22/05/1988 000092b

If the object length is shown as six digits, it is in a Small Directory,
if it is shown as eight digits, it is in a Big Directory.

When you do a B*INFOb on the root directory, the display includes
information on that drive, eg:

B	$          00064000 00015556  000300   DL/        22/05/1988 000047b

This gives disk size in the load address, the flags and ID in the
execution address, and the date the disk was created.


D*INSTALL (<drv>) ($) (<name>) (D)(S)(L) (<size>)			Filingd

This very important command creates an HADFS disk, installing on it the
required DFS files to partition it and setting up the root directory (I$i).
B*INSTALLb can be used on disks that already have HADFS installed on them to
install the current version of the software, or to change the disk name.

If the B$b parameter is given, then a new root directory is created,
effectively deleting everything on the disk. You must give the drive
number and a name when using the B$b parameter. Also, the command must first
be B*ENABLEbd.

A floppy disk must already be formatted as an HADFS or DFS disk, either 40
or 80 track, single or double sided. You can do this with the B*FORMb
command, which will create a blank HADFS Data disk. HADFS works best with
80 track double sided disks, but you can specify other size disks with the
B<size>b parameter in either number of tracks or number of sectors.

Using the BDb prefix will create a data-only disk by leaving off the DFS
installation files. The B<size>b parameter can be one of the following:

	B<dec>b	number of tracks, eg 160 for 80 track double sided.
	B<dec>Kb	size in K, eg 400K.
	B<dec>Mb	size in M, eg 64M.
	B&<hex>b	the total number of sectors, eg &640

All of the above examples, except 64M, give a size parameter for a
standard 80 track double-sided HADFS disk. If the size is followed by B*2b,
then the disk is a split disk, that is, a disk with less than 80 tracks on
one side. An example of this is a 40 track double-sided disk. This would
be B*INSTALLbed with B40*2b as the size parameter. If no size parameter is
given, then a size is looked for on the disk. If there is no size already
on the disk, ie it has never been B*INSTALLbed before, a BBad numberb error
will be generated.

The B<size>b can be prefixed by BDb, BSb or BLb:

	D	create a Data disk with no HADFSROM file
	S	create a System disk with an HADFSROM file (the default)
	L	create a Large directory structure even if smaller than 16M.

These prefixes can only be used when creating a blank disk. As an example,

	B*INSTALL 0 $ DataDisk D40b

would install a 40 track disk as a 98.5K HADFS data disk. If you use the
command

	B*INSTALL ?b

a brief reminder of the size parameters is displayed. The B<name>b can be
one to sixteen characters long, but should be at least two characters and
should start with a letter to distinguish it from a drive number.


D*LIB (<dir>)							Filingd

This sets the library directory to the directory given. The library
directory is where machine code command files are searched for if they
cannot be found in the current directory with B*b and B*/b. The search path
followed to find a file to run is shown below. If a file is found, it is
loaded and executed, else the search path is followed onwards towards the
end. So B*KEYb is matched as the MOS command to reprogram a function key,
B*/KEYb bypasses the MOS and is sent to HADFS to search for a general
command file, and B*RUN KEYb would look for a machine code file in the
current directory only. After a B*MOUNTb, the LIB is set to I$.Libraryi on the
mounted disk if it exists, or to I$i if it doesn't.

D*LIST <afsp>							DFS/MOSd

This command displays the contents of the named file on the screen, with
each line of text preceeded with a line number, starting at line 1.


D*LOAD <afsp> (<addr>)						MOSd

This loads the named file into the computer's memory, starting either at
the specified address, or at the file's own load address if no loading
address is specified. If the high byte of the load address is &FF, ie
addr=&FFxxxxxx, then the file is loaded into I/O memory. If the high byte
is not &FF, then the file is loaded into language memory.

A load address of FFFDxxxx will load into shadow screen memory, regardless
of which memory is being used to display the screen.

A load address of FFFExxxx will load into whichever memory is currently
being used to display the screen

A load address of FFFFxxxx, or if there is no shadow screen, will load
into normal I/O memory.


D*MAP (<drv>)							Filingd

This displays the free space map for the selected drive, or the drive of
the CSD, if none is given.


D*MOUNT (<drv>)							Filingd

This abandons any open files and dismounts all the disks preparatary to
inserting a new disk. You should always use this command, or B*BYEb, before
changing a disk, as directory information is kept in memory to speed up
disk accesses. If no drive parameter is given then the default drive,
usually drive 0, is mounted. After a B*MOUNTb, the  CSD and URD are set to I$i
on the mounted drive, and LIB is set to I$.Libraryi if it exists on the
mounted drive, or I$i if is doesn't.


D*OPT (<n> (<n>))						MOSd

This is used to set various file options. These are:

B*OPT 0b    - This resets OPT 1,2,3,6 and 7 to their default values.
                      B*OPT 0,255b also writes the B*OPT6/7b setting to CMOS.
B*OPT 1b    - Sets level of file information messages given on LOAD and
	SAVE commands: 
	B*OPT 1,0b	gives no messages (default).
	B*OPT 1,1b	gives detailed messages.
B*OPT 2b    - Sets the filing system number returned by OSARGS 0,0. With
	this you can make HADFS pretend to be a different filing system,
	eg setting B*OPT 2,5b will make it be recognised as NFS. Default is
	16, and you cannot set to 4, as that is the value of DFS.
B*OPT 3b    - Sets the auxilary filing system recognition number. A
	filing system can be selected with service call &12, and HADFS
	recognises the OSARGS 0,0 number set with B*OPT 2b and the number
	set with this call. 
B*OPT 4b    - This sets the autostart action as follows:
	B*OPT 4,0b	ignores B!BOOTb
	B*OPT 4,1b	B*LOADbs B!BOOTb
	B*OPT 4,2b	B*RUNbs B!BOOTb
	B*OPT 4,3b	B*EXECbs B!BOOTb
	B*OPT 4,8+nb sets the autostart option and sets the user as a system user.
B*OPT 5b    - unused.
B*OPT 6/7b  - set drive to use internal or external drivers:
	B*OPT 6,db	drive d uses internal drivers
	B*OPT 7,db	drive d uses external drivers
	After B*HADFSb, B*MOUNTb or B*BYEb the first access to a drive numbered
	0 to 7 first tries to use an external driver with OSWORD 90. If no
	external driver is found for that drive a flag is set to use
	internal drivers for that drive. Using B*OPT 7b can force a
	particular drive to always use external drivers, giving the BDrive
	x not presentb error if there is no driver. B*OPT 6b returns to
	allowing internal drivers to be used. The setting is saved in CMOS
	configuration RAM.


D*RENAME <old fsp> <new fsp>					Filingd

This command renames an entry to give it a new name. If the entry is
locked, or the new name already exists, you will get a BFile lockedb or BFile
existsb error. You cannot rename across disks, and you cannot rename the
root I$i directory. If you try to rename a directory inside itself or a
subdirectory, you get a BCircular renameb error.


D*RUN <afsp> (<parameters>)					MOSd

This command is used to load and run machine code programs. It loads a
file into memory, and then jumps to its execution address, unless it is
&FFFFFFFF or the load address is &FFFFFFxx when the file is B*EXECbed
instead. If the file's load address and execution address disagree about
which memory the file should run in, (ie, the top byte of the addresses
should both be &FF or they should both be not &FF), then the error BCannot
run this codeb will be generated. Using B*<afsp>b or B*/<afsp>b is the same as
B*RUNb, except that the library directory is also searched. See B*LIBb for
more information.


D*SAVE <fsp> <start> <end>|+<length> (<execute> (<reload>))	MOSd

This command takes a copy of the specified section of memory and writes it
to a file with the given name. If the execution or reload addresses are
not given, then they are set to be the same as the start address. If the
start address's high byte is not &FF, ie start<>&FFxxxxxx, then language
processor memory is saved. With a machine with no second processor, this
will be that same as I/O processor memory. If the start address's high
byte is &FF, is start=&FFxxxxxx, then I/O processor memory is saved.

A start address of FFFDxxxx will save shadow screen memory, regardless of
which memory is being used to display the screen.

A start address of FFFExxxx will save whichever memory is currently being
used to display the screen

A start address of FFFFxxxx, or if there is no shadow screen, will save
normal I/O memory.


D*SETDATE (dd/mm/yy (d))					Utild

When files are created, they are date stamped. On Master computers, the
date for this is fetched from the on-board Real Time Clock. The pre-Master
BBCs, however, do not have this feature, and so using this command
simulates the date part of it. After using the B*SETDATEb command, you can
read the date using the OSWORD 14 call, as on the Master. If there is an
on-board Real Time Clock this will take precedence to the date set with
B*SETDATEb as long as the code to access it is in a higher priority ROM than
the HADFS. The optional parameter Bdb can specify the day of the week 1 to 7
for Sun to Sat. Using B*SETDATEb with no date disables the function.


D*SETEXEC <afsp> <addr>					Utild

B*SETEXECb sets the specified file's execution address to the supplied
hexadecimal address.


D*SETLOAD <afsp> <addr>					Utild

B*SETLOADb sets the specified file's load address to the supplied
hexadecimal address.


D*SETTYPE <afps> <addr>					Utild

B*SETTYPEb sets the specified file's load and execution addresses to the
RISC OS-compatible filetype. The load address is set to &FFFxxx00 with xxx
being the supplied value.


D*SHUT								MOS/Filingd

B*SHUTb is similar to B*CLOSEb in that is closes all open files. On Master
series computers it closes all open files on all filing systems, leaving
the current filing system selected.


D*SPOOL (<fsp>)							MOSd

This command opens a file with the specified name to recieve all the
information subsequently displayed on the screen. It is the opposite of
the B*EXECb command. B*SPOOLb with no parameter closes any opened spool file.


D*STAMP <afsp>							Transientd

Sets the date attribute on the specified object to the current date.


D*STATUS HADFS							MOSd

This displays HADFS's current configuration status, that is, the number of
channels, which drives are using external drivers, and the current time
and date setting. On the Master series (or BBC series with suitable
support), the settings are saved in CMOS RAM.


D*TIME								MOSd

This command produces a standard display containing the day, date and
time, if set. On Master computers, the time will be read from the Real
Time Clock. If no RTC is present, then the date can be set with B*SETDATEb,
and the time can be set with BTIME=((minutes*60)+hours)*60*100b. The format
of the display is DDD,dd mmm yyyy.hh:mm:ss, ie Day, date, month, year,
hours, minutes, seconds.


D*TITLE (<drv>) <title>						Filingd

This will change the disk title on the currently selected or the specified
drive. The title can be one to sixteen characters long, but should be at
least two characters long, and should start with a letter.

The B*TITLEb command is an alias for the B*INSTALLb command, and will accept
B*INSTALLb parameters.


D*TYPE <afps>							DFS/MOSd

This command displays the contents of the named file, as with B*LISTb,
except that no line numbers are generated.
