As is the norm, I think that David is right here. Your command:
spawn, 'mkdir '+output_dir, message
will not have any output unless there is an error in the creation. So
the statement:
IF ( string(message) ) then begin
is a little odd as you are testing '' (nothing), with IF. You
probably want something more like:
IF strlen(String(message)) ne 0 then begin ;; print an error message
and go about you business

The reason that you are never hitting the STOP is that the IF
statement is never true.

Cheers,

Brian
