There are a couple of ways you can accomplish this. One way, as already
pointed out by Stein Vidar, is to end each line within a loop with the
characters "& $", so that IDL treats it all as one line. As I recall, this
works unless the loop is very large.

Another way is to use two procedure files. One file will contain the
main-level program that you wish to run. For example, let's say you save it in
a file called myprogram.idl. The second file will then contain the single line

.run myprogram

You can then pass the name of this second file to IDL. For example, if the
second file is named run_myprogram.pro, then the statement

idl run_myprogram

will execute the main-level procedure myprogram. It would be just the same as
if you had typed ".run myprogram" at the command prompt.
