lcCmd=[Pkzip25 -add=update "]+slcZipName+ '" '+lcList+' >'+ForcePath('zip.log', ;
   fullp(set('dire')))+chr(13)+chr(10) ;
   +'exit '+chr(13)+chr(10)
=strtofile(lcCmd, curd()+'zipit.bat')

cmdl=fullp(curd()+'zipit.bat')
lcThere=fullpath(".")
oProcess=NewObject('api_apprun','process', '', cmdl, lcThere, 'HID')
oProcess.LaunchAppAndWait
Release oProcess

This works for me - and as you see I'm creating the batch file on-the-fly. One thing, though: note the full paths everywhere.
