SUBMIT PROFILE.SUB Everytime you power up or reset your computer, CP/M 3 looks for a special SUBmit file named PROFILE.SUB to execute. If it does not exist, 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. HELP>
