The SUBMIT Command CP/M 3 User's Guide
the argument SAM is substituted for every $1 in the START.SUB file,
and TEX for every occurrence of $2 in the START.SUB file. SUBMIT
then creates a file with the parameter substitutions and executes this
file. This file now contains the following commands:
ERA SAM.BAK
DIR SAM
PIP SAM= A:TEX.COM
If you enter fewer arguments in the SUBMIT command than parameters
in the SUB file,, the remaining parameters are not included in the
commands.
If you enter more arguments in the SUBMIT command than parameters
in the SUB file, the remaining arguments are ignored.
To include an actual dollar sign, $ in your SUB file, type two dollar
signs, $$. SUBMIT replaces them with a single dollar sign when it
substitutes an argument for a parameter in the SUB file. For example,
if file AA.SUB contains line:
MAC $1 $$$2
and you enter the following SUBMIT command:
A>SUBMIT AA ZZ SZ
then the translated file contains the following:
MAC ZZ $SZ
Program Input Lines in a SUB File
A SUB file can contain program input lines. Any program input is
preceded by a less than sign,
