SM Move to the system maintenance subsystem. See chapter 16 for more
details.
SY Enter the BASIC shell and Monitor. Here, you may actually use BASIC
on-line! You may use the shell to write programs, edit programs (even
C-NET files), and even run programs. The used areas in the 128’s
memory banks 0 and 1 are ‘blocked off’ from BASIC access by
manipulation of the start of basic text and variables memory
locations. All BASIC I/O, however, is still routed through C-NET’s
ML, allowing CONTROL-S pausing, SPACEBAR aborting of text output, etc.
C-NET runs in COMPLETE and total Commodore screen emulation, allowing
cursor movement, quote mode, insert mode, and everything else. C-Term
has been adapted to do the same (using the CG+ mode). Because C-NET
itself must still reside in BASIC memory, there are restrictions.
These include:
(1) Lt. Kernel commands MAY NOT be used (because of conflict
of memory problems). Use DLOAD, SCRATCH, DSAVE,
DIRECTORY instead.
(2) Files #131, #6, and #4 may not be used (a CLOSE131 or
CLOSE6
will disable your system completely).
(3) Graphics/Music/Sprites will cause sure disaster! A simple
matter of no extra memory to put that type of
program.
(4) Poke/SYS calls are asking for trouble. Even SYSO isn’t
guaranteed to work; this means that MCI commands are not
usable. Use control codes directly within PRINT
statements to move the cursor or change colors.
(5) Approximately 85 blocks (the same as for a p-file) is the
amount of BASIC workspace available. Attempting to DLOAD a
file that is too long will crash the system.
(6) To exit back to the Main command level, enter ‘q’ (must be
lowercase) at the first column of a BASIC input
line.
EM This command controls entering the Main Macro editor. You will be
prompted to edit each macro by number. There is a maximum of 25
allowed at the Main prompt, but may be changed by editing the CN file at
line 1301.
NT This command allows you to ‘test’ any of the Multi-Net files without
having to run the entire network. It will prompt you for a file name.
When you enter the file name, you only need to add the portion AFTER
the dash in the file name. For example, if you would like to see the
‘prg.net-subs’ in action, then you only need to enter ‘NT’ and when
prompted, enter ‘subs’. The ‘NT’ file will automatically add the ‘net-
’ portion of the file name for you, and then ask if you would like to
have the TRACE command active (makes things difficult to read, but it is an
EXTREMELY useful de-bugging tool). It is important to note here that
‘Testing’ the p-file assemble will cause C-NET to run all the way through
the network.

9.0 THE ACCOUNTING SYSTEM
You may use C-NET’s accounting system to ‘charge’ users or to give them
‘credit’ for thirteen items:
