How to get file UNIT from file NAME? [message #58885]

Hello,

Is it possible to get a file UNIT from a file NAME? For example, in Fortran95 you can do,

INQUIRE( FILE=Filename, NUMBER=FileID )

i.e. supplying a Filename yields its associated unit number, FileID (which is -1 if no
unit is connected to the file)

Is there an equivalent IDL command? FSTAT requires one to supply a UNIT argument, which is
opposite of what I need, i.e. similar to the f95

INQUIRE( UNIT=FileID, NAME=Filename )

Basically I want to be able to derive all the necessary info about the file, in particular
answering the "Is it open? If so, what unit number?" questions just from the filename.

Any info appreciated.

cheers,

paulv
