Oh my - let's me try this again hopefully with fewer typos...lol.  Also 
a bit more clarification.

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

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 execute (for example):

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

Obviously your pushkey needs to be above the browse line in the 
program.  At least initially.  I can see how one might reuse pushkey as 
part of browse processing under certain conditions.
