I think you are trying to run the IDL SAVE files like an executable
program.  It is not executable!  The garbage you are seeing is the
Unix shell trying to interpret the binary data as shell commands.  I
think you will still have to make a small script which loads the SAVE
file and runs the right start-up function.  You could do something
like this:

--------
#!/bin/sh
idl << EOF
path = '/home/leonid/'
restore, path+'Xe.sav'
leonid_main
exit
EOF
--------

You will have to make this executable, be sure the path is correct,
and define leonid_main to start whatever programs you want to start.

The comments by R. Bauer about resolving all of the routines are
probably appropriate too.
