ah ok,
what about writing a small program that search for all .sav files, then,
in a loop, call a procedure that open the sav files and do a save, /all
/compress with the same (?) filename. (the extra procedure is to make
sure that only the variables of the current sav files are in scope and
saved)

Maybe I did not explain well the problem...
The savs are already done and I would like to compress them
individually, in a manner that the programs that open them will not
notice.
To use the keyword /compress is what I should have done and I
didn't ;)

This worked, THANKS!
In fact, the files were not mine, but used a lot of disk space! :P

I might be a little late but I'd just like to say that you can also
compress any files/directories by spawning the tar command. For example,
here's code that compresses a file:
spawn, 'tar czf "'+PathToCompressedFile+'.tar.gz"
"'+PathToFileToBeCompressed+'"
