You will find the same trace parameters in above shared linked.
Just to make it handy add below in batch startup pf file (make sure you do this Dev / test environment). As trace log files grow faster.
Use below in .pf file
-clientlog c:\temp\4gltrace.log
-logginglevel 4
-logentrytypes DB.Connects,4GLMessages,4GLTrans,4GLTrace
Turn it off once you get the trace file and parse it to get the list of programs. In program you can achieve the same with LOG-MANAGER.
