Hey IDL Wizards,

The IDL code, in this case, is .COMPILEd and SAVEd for execution from
the Linux command line.

The execution is done with a Perl wrapper that writes a namelist with
options for the IDL code.

my $result=exec("/usr/local/bin/idl -quiet -queue -rt=\'$idl_executable
\' -args \'$namelist_file\' 2>&1");

I was hoping that the "2>&1" would push the IDL output to STDOUT, but
no such luck.

I can't even lay odds as to whether this is a Perl thing or an IDL
thing...
