I think it is better to use perl (or sh) with IDL to do this. The
nicest way is like this:

#!/usr/local/bin/perl -w

open(IDL, "|/usr/local/bin/rsi/idl/bin/idl") ||
die "Can't open IDL: $!";
$\="\n";

print IDL "var1 = $ARGV[0]";
print IDL "var2 = $ARGV[1]";

print IDL "doit_procedure, var1, var2";

##etc. You can loop over filenames:

foreach $filename (glob(*)){
print IDL "process_file, '$filename'";
}

print IDL "exit";

I've also written perl scripts that create long IDL scripts that I can
then check over and run, for example to convert a bunch of BMP files
to several files of raw 3D data:

#!/usr/sbin/perl -w

$\ = "\n";
$outdir = "/data1/stuarts/calsim/spatial/surrogate1/";
$indir = "/data1/eo1/jam/";

print "get_lun, F";
foreach $suff (qw(1 b c d e f g h i j k l m n o p q r s t u)){

$outfilename = $outdir . "data" . $suff;
print "openw, F, '$outfilename'";

for ($x = 0; $x < 200; $x++){
$filename = $indir . "data" . $suff . $x . ".bmp";
if (-f $filename){
print "frame = read_bmp('$filename')";
print "writeu, F, frame";
} else {
die "$filename not found\n";
}
}
print "close, F";
}
print "free_lun, F";
print, "end";
