Hi Richie!



RM> I'm new to programming for OS/2 so naturally I have a question.  :)

:)

RM> When using the dialog editor, how does one implement the notebook
RM> object?  That is, in order to have multiple pages.  A snippet of code
RM> for 2 or 3 pages ( small ones ) would be most helpful.  Thanks.

I hope, this will help you:
