I am working for Xtravision. To operate the till and to keep track of
the DVDs and tapes we have in stock we use a very old DOS program
called "Pick". I am finding it hard to get used to the program and I
would like to get a hold of a manual or at least some sort of tutorial
for the said program. That way I could research and learn the program
in my own spare time.
Any attempts I have made to search for the said program have been in
vain. I guess my question is "Where can I find information about this
program, its uses and limitations, and possibly a manual and/or
tutorial?"
Since it's a PC program there simply MUST be info about it SOMEWHERE
on the internet. It's not as if it's a classified secret..
