Write your reply.

assistant: still would be interested in hearing......
this is one reason I go looking for all the source code I do - it's amazing
how some of the so-called "indespensible" OCX's can be dumped when you use
the right code.
discovered that the hard way <g>
 I honestly didn't realize that this could be done and not have it 'puke' on
compile. Thanks......
 Have only really just begun to understand this concept, but gotta admit it
sure makes things alot easier.
It still surprises me how something that would seem so logical to do doesn't
register until some-one else mentions it. again thanks
BUT here is a question on this.... when setting up your Global "Module"
variables is there a theroretical limit of the number of variables that can
be declare - or maybe a better way to put it... is there a 'good programming'
limit?
'Til next time ......
