There is no problem with portability esp. if you change the name
of the procedure to keep the original.

The other idea, to save the parameter in a file, will only be helpful
when you need this for some other reason (log file).

You may save the parameter in a common block. Although common
blocks are not loved by those programmers who favour structured
programming, this feature is well implemented in IDL and can be used
quite efficiently. BTW it's a lot faster to access variables via
common rather than passing structures via a parameter list!
