Executing Multiple Commands; Terminating Programs; Getting Help - Commodore 128 System Manual

EXECUTING MULTIPLE COMMANDS

ln the examples so far, CP/M 3.0 executed only one command at
a time. CP/M 3.0 can also execute a sequence of commands.
You can enter a sequence of commands at the system prompt,
or you can put a frequently needed sequence of commands in a
disk file, using a filetype of SUB. Once you have stored the
sequence in a disk file, you can execute the sequence whenever
you need to with a SUBMIT command.

TERMINATING PROGRAMS

You can use the two keystroke command CTRL-C to terminate
program execution or reset the disk system. To enter a CTRL-C
command, hold down the CTRL key and press C.
Most application programs that run under CP/M and most CP/M
transient utilities can be terminated by a CTRL-C. However, if you
try to terminate a program while it is sending a display to the
screen, you may need to press a CTRL-S to halt the display
before you enter CTRL-C.

GETTING HELP

CP/M 3.0 includes a transient utility command called HELP that
displays a summary of the format and use for the most common
CP/M commands. To access HELP, simply enter the command:
A >HELP
You can press the HELP key instead of typing the word HELP
and pressing the RETURN key.
