I need to display 30 rows of an Excel 2003 worksheet, pause, page down,
pause...etc until I reach the bottom, the go to the top and start all over
again.
I was given a .WAIT application that works. I created a command button,
right-clicked on it, then clicked on "View Code", pasted the code in there
and it worked
fine. It needs to run for long periods of time and I was warned I could run
out of stack space. My system does crash if I run it a long time.
I was also given code for an ".ONTIME" application. I tried pasting this
under the "View Code" of the "Command Button". This does not work. I'm not
familiar with the Excel environment. I guess I need simple instructions on
where to put this code. I do want to activate the code with a command button.
The code is listed below. Thanks in advance.

This version is a bit more stable. As you cannot pass parameters in a call
to .OnTime, use public variables to pass settings:
SHIFT+ESC to halt execution.
