It may be useful in the UILess program to use the Sleep() API call in your loop. Such as:

DECLARE Sleep IN Win32API INTEGER nMilliseconds

do while .t.
   if file("myservice.txt")
       *** Code to open DBF, look for records, and process
   else
       exit
   endif


   =Sleep(100)
enddo

This pauses the program for a tenth of a second every time around.

This should make the PC running these EXEs more responsive than if it were stuck in a tight loop.
