Subject: SD102 Super Directory program now available
The latest verion of SD, the "Super Directory" program, is now
available from SIMTEL20 as:
Filename Type Bytes CRC
Directory MICRO:<CPM.DIRUTL>
SD102.LBR.1 BINARY 77952 BCA1H
SD displays the directory of a CP/M disk, sorted alphabetically, with
the file size in k, rounded to the nearest CP/M block size. Also
displays library files with the file size in k if the '$L' option is
used. This version can be assembled with ASM, LASM, MAC, RMAC or M80.
Latest revision:
10/31/85 Fixed bug which caused system to crash if BYE low (LOWCCP)
v102 and using disk options (DOPT EQU YES). Thanks to Wayne
Masters for reporting it.
- Keith Petersen, W8SDZ
Current versions of SD automatically adjust for any block size and
directory length under CP/M 1.4 or 2.x or MP/M (any version). They
also automatically adjust for any number of disk drives and work
satisfactorily even if no disk is in that drive at the moment.
Provisions are made for:
(1) automatic pauses when the screen fills up
(2) searching individual or multiple drives and/or user areas
(3) unconditional or optional resetting the disk system before
execution begins
(4) directing output to a disk file called SD.DIR and appending
to that file on subsequent runs
(5) summary line output giving drive and user information,
number of files matched and how much space they consume,
and the amount of free space remaining on the disk
(6) displaying or suppressing "system" files
(7) accepting ambiguous filenames with or without a drive name
(8) printer output
(9) optional help menu with $?
Previous revisions:
10/28/85 Added an equate to allow display of file attributes only in
v101 inverse video. This leaves the header line in normal video
and avoids that bright band on the screen. Also, with the
THREBYT equate set, the third byte was written to the disk
when the F option was active. This mod fixes that problem.
- Barron McIntire
07/24/85 Rewrote the TIMEON code to allow use of the existing time-
v100 on-system data contained in BYE5, BYE3, BYE+ or MBYE's RTC
buffer. If TIMEON is YES, SD merely reports "Time on system
is nnn minutes" and makes no attempt to log the user off.
Logoff responsibility is delegated to the (M)BYE(+) program.
TIMEON checks to see if BYE is running and continues without
reporting time-on if not. No installation required to use
this feature if you have clock code installed in your BYE.
All page-1 equates previously used by TIMEON were deleted.
This update also contains the SD99.FIX code for nested IF'
- Wayne Masters, Potpourri
07/11/85 Added THREBYT equate for systems needing a 3-byte sequence
v99 for reverse video. If THREBYT is YES then the value coded
at TBYTE is added to the reverse video sequence (currently
set for a Kaypro). Also added a new "?" option which will
display a menu of the $ options available if HELP is YES.
- Steve Sanders
03/15/85 Fixes obscure display bug which deletes display of 1, 2 or
v98 3 file names in 3 out of 4 cases when the directory has
>255 entries. The fix code was written by Peter Lyman.
- Paul Foote
01/21/85 Added support for ZRDOS. Although CP/M compatible, ZRDOS
v97 does not allow the SWAPEM technique of poking local values
into the operating system. Instead, a test for ZRDOS is
made and, if present, further calls to CPM: set the Warm
Boot Trap in ZRDOS. On any error detected by ZRDOS the
trap is reset and control is passed to DSKERR: No equates
need be changed for CPM/ZRDOS, testing is dynamic in the
run-time code.
