If EMPS.EXE is in the c:\temp directory, then I expected the result from the command below to be "c:\\temp" but it does not have the double slashes. I tried it with "ZZ" instead (just for fun) and it does replace the slash, but with only one Z, not double Z. I don't get it.

? CHRTRAN(JUSTPATH(FULLPATH(SYS(2000,'EMPS.exe'))),'\','\\')
