[Coco] SysCall source listing

[Wayne Campbell]

Thanks, Robert, but I already have that one, and the module included with
Level 2 is identical in size to the version included with NOS-9 Level 1 and
Level 2, and with the 6309 flavor as well. I will have to look at my notes
tomorrow to be sure, but I believe they all proved to be identical in
comparison using CompareIt!.

Your words actually verify what I have thought, and that is there was no
SysCall until OS-9 Level 2. Not that it didn't exist, just not in the Tandy
version of Level 1.

I don't know if there are any list members who used to run OS-9 on other
platforms, or used Basic09 under Level 1 and ever used a SysCall subroutine
in a procedure.

I am willing to call SysCall a new-for-level 2 inclusion. It seems strange
though, after touting Basic09 as usable as a systems programming language
to not include a means of doing system calls...
