You can try,
CMSAVEDIR, 'filename.sav'
to get a list of the contents.
And if you want to append something to the file,
CMSAVE, new_variable, FILENAME='filename.sav', /APPEND
Note that these routines were eventually sanctioned by the makers of
IDL. I paid dearly to have them be public, so people might as well
use them if then need them.

After restoring your file, type the "help" command.
You should see something like:
IDL> restore,'myfile.sav
IDL> help
% At $MAIN$
A INT = 3
B INT = 2
Compiled Procedures:
$MAIN$
Compiled Functions:
IDL>
i.e. the variables stored in the save file should just end up in your
current scope.
Thanks,
Allan

If you just want to see what is in a save file, and maybe
selectively restore variables and such, you can use
the IDL_Savefile object to do so. This object doesn't
allow you to add to the contents.
Cheers,
David

I see. Thanks. I am a noviece IDL user. I have read a lot about
the .sav file in this group. I tried the "RESTORE" routine, but seems
like I still can not see the contents and add anything I want in it.
Thanks anyway!

It's unclear (to me, at least) exactly what you want to do.
You can restore the contents of a .sav file at the IDL command line by
typing:
restore,file='myfile.sav'
and you get the contents to play with which you can later save.
If you had a .sav file with two varibles, say a and b and you wanted to
increase the value of a by 1 then you would type:
restore,file='myfile.sav'
a=a+1
save,a,b,file='myfile.sav'
If you're looking for something with more power then see:
http://cow.physics.wisc.edu/~craigm/idl/cmsave.html
and if you're looking for something which does even more then see
David's reply.
Thanks,
Allan

No, and don't even try. We don't need *that* police scene
again. :-(
