OR *program input* - which is why Bill mentioned using pushkey.  And 
actually I believe processing stops then either all records have been 
selected that can be shown OR when filepro has enough records selected 
to show to fill up one browse screen's worth.

And there is - pushkey.  Keep in mind that the "exit key" defined in the 
browse can be almost anything.  It could be "P" for "proceed!". It 
shouldn't be advertised to the end user - it's only needed in 
conjunction with @bk to allow you to have the program execution (for 
example):

a) clear a message, then
b) repeat the browse with "pkeep" on the keep the place in the browse

Obviously your pushkey needs to be above the browse line in the program.
