IDL makes the distinction of what can be run on the command line, and
what can be placed in a compiled procedure. Items that appear on the
command line are more restricted. For example you can't have
multi-line BEGIN/END clauses, which is exactly what you are seeing.
This is also the distinction between the "@" command, and the ".RUN"
command. The former accepts only simple commands, while the latter
expects a fully formed procedure, finished with END, but is able to
take BEGIN/END clauses. The EXECUTE() statement, upon which
executeIDLCommand() must be based, also falls in the former category,
so that's why you are getting errors. Why don't you just stuff all
this into its own procedure?
Good luck,
Craig
