Results from commands.
If a command returns a value or information, the data will generally be
returned in the RESULT variable. The only exceptions to this are the
dopus getdesktop , dopus getstring and lister getstring commands
which return information in the special DOPUSRC variable.
Error codes are returned in the RC variable.
You must include the line "OPTIONS RESULTS" near the top of your script
to enable the RESULT variable. See an ARexx manual for more information.
