>ON ERROR DO ErrorRoutine WITH ERROR(), MESSAGE(), PROGRAM(), LINENO(1)
>This passes error number; error message; program, method or event where error occurred, and line number in program, method or event where error occurred.

Again, the documentation is ambiguous enough that the solution i was searching for was overlooked.

I assumed the "name of the currently executing program" would always be the .exe or the .prg/.fxp If the word was module instead of program, i'd have at least tried it. eh, i guess it's my own shortsightedness...

Thanks a 1E+6!
