The problem is not that a function may have changed in IDL 5.3. The real
issue is that the format of SAVE files which include compiled routines
is different in IDL 5.3. However as David pointed out, SAVE files which
include only data (variables) are backward and forward compatible.
Cheers,
Liam.

Well, they *might* work, but in your case it sounds like you are using a
new/modified IDL 5.3 function. I doubt that their entire internal
structure changed. In general David is right - it should't be expected
to work. Kinda stinks if your are distributing applications
because you need to have maintenance on ALL platforms ($$$).

BTW - bnl is Brookhaven National Lab? Need any IDL freelancers? I'm
local (in a physical sense).

IDL SAVE files are not generally backward compatible,
except for saved data. It is highly unlikely that
SAVED routines (which is what we have here) will
run in a previous version of IDL.
