EXIT terminates the current operating mode of the program.
EXIT ;
Usage
If used in interactive mode, the interactive session will be terminated, returning control to the operating system; this is the same as typing STOP or END.
If used in collect mode, this command will return the user to the interactive level of the program WITHOUT executing the commands just collected (use the EXEC command to leave collect mode with automatic execution). EXIT may also be used to replace END at the very end of an INPUT file to suppress automatic execution upon completion of reading the file (see INPUT).
