Subject: CP/M & MBASIC question

       Greetings I have a Kaypro 10 and am starting to experiment
       with CP/M. (My first z80 machine)

       I have several questions:

       1) Is there a command in Miscrosoft BASIC (M-80) that will
       clear the screen and home the cursor? I have all docs but they
       say nothing.

       2) I have a simple CLS.COM program that is about 15 bytes long
       that clears the screen. Now, I DUMPed it and converted the
       hex to decimal and poked those values from within BASIC.
       When I CALL it, it clears the screen and does a "Warm Boot"
       [bummer]. Anyways, I got rid of the JMP 0000h (for the
       warm boot) but now in hangs. [bummer^2] Arghh... Good lord,
       even my Apple ][+ has a HOME command! ;-)

       3) How do I load a binary file so I can use it with the
       USR# function? I have an assembler (RMAC), a linker, a
       BASICLIB.REL (what is that <--- ?), and MBASIC. Is this
       all I need? Oh, yeah, I have a hard disk so space in not
       a problem.

       (I have the source for SAFETY.COM, which also clears the screen,
       but even that does not work when POKEed from BASIC. Can I use
       &HD000? I have no idea where empty space is in BASIC.)

       Anyone?

       I also don't have a text editor (WS died) so I wrote my own
       in basic.... can't use the "," with INPUT... it gives a
       "Redo from start" (or something similar).

       4) Anyone know how to read a text file using random-access?
       I tried every possible combination. I can create but I can't
       read it. (Remember, you can't read a file that contains ","s
       with the INPUT# statement)

       Maybe I should stick to assembly..... [grin]
       (Yeah, but you need an editor for that - Catch 22???)

       Take care.

       P.S. Please e-mail. I will archive everything. Before sending
       a "send everything to me", give me a few days to organize :-)
