That is how I managed to do it, but I like to think of it as
'very purty' as opposed to 'not very pretty'.

Here is my script. I name it "idl_argv.pl", and here are some examples
of how to call it (from the unix prompt):

./idl_argv.pl
./idl_argv.pl 's = "a silly string"'
./idl_argv.pl 'for i=0,10 do print, i'
./idl_argv.pl 'foo=42 & help, foo & plot, indgen(foo)'
./idl_argv.pl 'pi=3.14159D & almost_pi = 4 ; spaces and comments!'

Here is the script:
----------------------------------------
#! /usr/bin/perl

$input = $ARGV[0];
@list = split( /&/, $input );
$uniq = $$;

open( IDL_FILE, ">idl.$$.pro" );
for ($i=0; $i<=$#list; $i++)
{ print IDL_FILE "$list[$i]\n"; }
close( IDL_FILE );

system( "idl idl.$$.pro" );
system( "/bin/rm idl.$$.pro" );
exit(0);
-----------------------------------------

Is this even close to what you were trying to do?

-k.
