Well, I've just been researching how to work with global variables, and found this thread. Concerning the June 30 reply by willir (Richard) above, I'd much appreciate if somebody would explain how this is done:
"- You can pass variables from sub routine to sub routine."
Now I do sometimes use functions from external modules that take variables in subroutines, but it sounds like he is talking about something much more powerful here.
Barring more on this, I'm ready to start trying out globals. Until now I've been using a technique of setting the value of an invisible text box, then taking its value in another form or report's subs. Thanks if anyone can shed more light here.
