Hi David,

this brings up an interesting legal/buisiness question: If
file_which is an IDL file (.pro) distributed with 5.4 is it then
permitted to use this routine with earlier versions of IDL (provided
it works)? Legally, I would think this should be doable at least as
long as you are under a maintenance contract, i.e. you could
theoretically run 5.4 but haven't installed it for whatever reason.
Without a current maintenance contract, there would be the question if
such a new library routine belongs to IDL5.4 or to IDL in general.
Buisineswise, it might be a smart move of RSI to put their library
routines under the open source license and post them own their web
site. Nobody without a licensed IDL program can use these routines
anyway, and it could be regarded as a nice service to the users if
they can profit from new developments in the library routines.

Just a thought,

Martin
