This is how I run an IDL program in batch mode with arguments.
Create a script file named batch_myprog like this:
---------------------------------
echo Running MYPROG
rm $1.out
rm $1.err
(echo .run myprog ; \
echo myprog, \'$1\' ; \
echo exit) | \
idl 1>>$1.out 2>>$1.err
---------------------------------
Make sure batch_myprog is set to have execute permission. (This example
is K shell, but C shell would be similar.)
In this case, MYPROG is an IDL procedure in the file myprog.pro. It takes
one argument (the name of file to be read by MYPROG in this case). The
script will print a message ("Running MYPROG"). Then it will remove files
called $1.out and $1.err, where $1 is the first argument to the script
batch_myprog when you run it. Then it will create an input stream telling
IDL to compile myprog and execute it with the value of $1 as the
argument. This input stream is piped to IDL.
To run the batch job use:
nohup batch_my_prog input_file_1 &
I use this where the argument $1 is a file name to be read by myprog.pro.
The output of the IDL job will be in input_file_1.out and
input_file_1.err. If you want to pass numeric arguments, you should
probably redirect IDL output to different files than $1.out and $1.err.
This is certainly not a generic solution, but for simple argument lists it
works fine. An alternative is to write the batch script arguments to a
file and then pipe that to IDL. This script avoids the intermediate file
by creating the input stream with 'echo'.

You can read your data at the top of the batch file,
with input redirected from a separate text file.
Here is an example, with an IDL batch file test.pro
reading input from the file input.dat
----- file test.pro -----
READ, A
READ, B
READ, C
HELP, A, B, C
----- END file test.pro -----
----- file input.dat -----
10
20
30
----- END file input.dat -----
Then from the unix prompt,
$ idl test < input.dat
A FLOAT = 10.0000
B FLOAT = 20.0000
C FLOAT = 30.0000

Hi Mark,
your question intrigued me, and I came up with a solution involving
a temporary file that is written by a little Unix shell script and
contains the arguments passed to IDL. This is certainly not perfect,
and I haven't spent any time on error checking etc., but it may provide
a start. I must admit that I have never tried to execute IDL in batch
mode before, and my 2-minute primer on this led to the conclusion that
you can only run main prorgrams this way and that you have to provide an
EXIT command in order to leave IDL after your program has terminated. If
this is not true, I'd be happy to learn more!
Now, here is how it works:
the shellscript idlbatch (make sure it's executable):
# Unix shell script to pass arguments into idl
# when running in batch mode
# uses echo to store the command line arguments in a
# temporary file which can be read by batchtest.pro
# Example: idlbatch batchtest 5 8
echo $* > tmpfile
idl $1
Your main program (see batchtest.pro as an example) will have to
read in 'tmpfile' and extract the arguments: the first argument is
the name of the program itself. In batchtest.pro I simply call a
second procedure batchtest2.pro (also attached below), which multiplies
the first two arguments (defaulted by a value of 3). Certainly, there is
lot of room for improvements on the parameter parsing and type
determination - who knows, maybe David is interested ?
Best regards,
Martin.

I implemented such a scheme by creating a unix shell which sets
up various parameters before running idl. The unix shell writes
into a file which is executed by IDL by means of the "setenv IDL_STARTUP ..."
scheme. The shell passes along arguments from the command line, which
may contain IDL commands.

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";

Here's a variation along those lines. You could set the environment
variable IDL_STARTUP to point to different batch programs, then call IDL.
This would start IDL and run the batch file pointed to by IDL_STARTUP.
Similarly, you could keep IDL_STARTUP pointing to the same file, but
create that file using your UNIX program (shell, perl, etc.). Get the help
of your local UNIX shell programming fanatic and you might end up with
something pretty entertaining. I was doing stuff like this a couple years
back. I could dig up some ideas from those efforts if you're interested.

As far as I know, this can't be done the way you want to
do it. You do have one other option, however. You can define
environment variables for your input parameters. Then your
bactchprog.pro program calls GETENV to get the values of
the environment variables before passing these onto the other
programs that you want to run in batch mode.
Naturally, the return value from GETENV is a string, so you
will have to take care to convert the value to a number, if
that is what you want, etc. I've never tried it myself, but
I think it is possible.
Cheers,
David
