Comment &
This program is designed to dump an ACCOUNTS-TABLE.BIN file into
another file that can be more easily read by people. It was originally
designed to produce a file(s) that can be re-read by ACTGEN. And
amazingly enough, as long as there are no sub-accounts in the file, it
works as intended! At sometime in the future it might even work for
subaccounts also...
The are a number of sections of code that have been commented out.
These sections were originally put in to write messages to the screen
for debugging purposes. However, it might be desirable to have these
available to the person using this program, so I left them in. If
these "features" are wanted, just uncomment them. I didn't even
bother commenting most of them, but they are pretty self expainitory...
Good Luck!!!

This subroutine can be called to ask for confirmation, and
should be called at the end of all parsing command strings.

This subroutine is used to pase a guide word for a command.
accepts in AC1, pointer to guide word string.
calling sequence:
