>>>I need to do a small change/update to a table residing on a customer's PC. I created a small .prg that does just that. I wonder if I can send them the .FXP (compiled version of the .prg) file and ask them to run it. Will it work? Or must I include the .PRG in a project?

You can create a wrapper EXE that can run any FXP/APP passed as parameter to it. Something like

LPARAMETER tcRun
DO (tcRun)
