The PROFILE.SUB Start-up File
Every time you turn on or reset your computer, CP/M 3 automatically
looks for a special SUB file named PROFILE.SUB to execute. If it does
not exist, then CP/M 3 resumes normal operation. If the PROFILE.SUB
file exists, the system executes the commands in the file. This file is
convenient to use if you regularly execute a set of commands before
you do your regular session on the computer. For example, if you want
to be sure that you always enter the current date and time on your
computer before you enter any other commands, you can create the
PROFILE.SUB file, with ED, and enter the DATE command as follows:
DATE SET
Then, whenever you bring up the system, the system executes the DATE
command and prompts you to enter the date and time. By using this
facility, you can be sure to execute a regular sequence of commands
before starting your usual session.
