Thanks! I need to try out some variations. Most of my users are familiar
with subfiles on green screens and will be expecting something similar
with PHP.

Kelly,

That will always return the first 50 rows.  Which is fine if that's all 
you want.  But folks often want to use this to load one page of records 
to be displayed, then after someone clicks the "next page" button, they 
want to display the next page of records.  (yours would result in the 
same page being displayed every time)

Here are some previous discussions you might find interesting:
