The SIG/M Report (December 1980)
by Bruce Ratoff
The SIG/M software library seems to have drawn great interest
from CP/M users both in and out of our geographical area. The
November SIG/M meeting at UCTI saw long lines of ACGNJ members
waiting to copy the available diskettes. Many thanks to Jeff
Kashinsky, whose system got a real workout doing the copying. A
number of individuals have volunteered their assistance in
distributing the library. Their names and phone numbers (some
BBS, some voice) appear below. It is hoped that this interest
will continue, for a group such as SIG/M needs broad support in
order to succeed.
One regrettable mishap has occurred in compiling the library
disks. Diskette number 4, a collection of CP/M utilities, was
defective at the time of the users' group meeting. Henry Kee, who
compiled this diskette, seems to have discovered (the hard way)
an incompatibility between Digital Research PIP and Cromemco
CDOS. The end result was several bad files. The diskette has been
re-created and verified, and will be available for copying at the
next users' group meeting. Those of you who received the
defective copies will of course receive a new one at no charge.

TIP-OF-THE-MONTH
Changing the CP/M 2.2 backspace: As many of you know, CP/M
version 2 allows hardcopy-style line editing, via the rubout and
control-U keys, as well as CRT-style line editing, via the
backspace (control-H) and control-X keys. As supplied, the CRT
editing keys use a "backspace, forward space, backspace" sequence
to erase characters from the screen. If your terminal requires a
character code other than control-H (08H) to move the cursor left
one character, you may patch the correct character into locations
1373H and 13ADH of MOVCPM. If you then use the modified MOVCPM to
create a new system, it will use the new backspace character that
you have designated.
If you have a CP/M question or know a "trick" that you would
like to see as a "tip-of-the-month", please contact me via either
the mailing address or telephone number listed above.
