Alternative to PROGRAM() and SYS(16,n)

Hi all

I want to find the path of the "master" EXE at some arbitrary point in code - and I need it to work within a method of a class defined as OLEPUBLIC. PROGRAM() and SYS(16,n) do not give me just the fully qualified path/name of the master EXE. I have come up with the following but I wondered whether anybody can think of a better/simpler solution. Thanks

=lASTACKINFO(laStackInfo) Return laStackInfo(1,2)
