Just as an aside, if you're doing this in IDL63, you could use the
IDL_IDLBridge object to run each script in a separate "clean" session of
IDL. This is also useful when you want to build multiple .sav files (with
IDL code) and you need to have a clean IDL session for each .sav file.
So for example,
o=Obj_New('IDL_IDLBridge')
o->Execute, "myscript, 'datafile1' "
Obj_Destroy, o
o=Obj_New('IDL_IDLBridge')
o->Execute, "myscript, 'datafile2' "
Obj_Destroy, o
If you use the /NOWAIT keyword then you could even have them all executing
simultaneously (although then you wouldn't want to destroy the object until
it finished...)

Thanks everyone for your quick responses. I was using a script
(@script), but I wanted to use the .reset_session command many times.
Here was a piece of my code:
for i=0, size(int_arr, /n_elements)-1 do begin .reset_session &
map_to_geo & endfor
So, the .reset_session command could be used in the script, just not
within an IDL statement. It would have worked if I only wanted to
reset the session once.
I just realized that all of my structures were named, so this problem
can be solved if I just make all of my structures anonymous.
OK, I made all the structure anonymous and I am running the code right
now.......
And it works!
Thanks for the help everyone,
Branch

By "script", do you mean a regular procedure? I know that you can do
.reset_session in a batch file (which you run by @filename).
Plus, if you redefine the structure all the time, why use a named
structure? If you use an unnamed structure, you can redefine it as often
as you want.
Happy programming,
Benjamin

True, but I would suggest the OP address the problem (assuming it actually is one) of the
structure redefinition. So, pardon my denseness, but could the OP define what he means by
"redefines the same structure".

.reset_session is an executive command; executive commands (all of the
commands that begin with a ".") can only be entered "in response to the
IDL prompt" according to the docs. You can put an executive command in a
batch file and call the file from the command line. For example, in the
file "batch_run.pro" put:
.reset_session
start_real_run ; call to your existing program
Then,
IDL> @batch_run
And it should work.
