I'm working on writing a program for CP/M 2.2, and
would like to make it
stay 'resident' in the system memory. Is there any way I can locate
to bottom of the CCP so I don't overwrite it, without doing it at compile
time? I'm planning on using only Z-80 based systems (so I can use an
offset-based jump) so I should be able to pretty easily make the code
re-locatable. All I need to do is be able to figure out where the CCP is
so I don't overwrite it.
<sigh>
CP/M Plus offered this through the RSX Manager.
Due to all the cool RSX utilities available from Jim
Lopushinsky back in '84, I was able to make CP/M 2.2
and Molecular's N*Star MP/M-II-ish OS a lot more useable.
I mistakenly told Allison that I thought I wrote this stuff!
I just plain got it confused with what I did write...
Anyway, write me privately, I don't want to post the ftp
url in a place that will be harvested someday...
