For me, it would be ideal, if I could do everything in IDL...but I don't
work in an ideal world... So I think your suggestion of an intermediate file
written by the original parser is probably the way to go, although I still
have the IDL parser on the back burner. That will give me a fall back, if I
can't get an ascii reader written in IDL by dinner time (as David Fanning
suggests :-)....
Thanks to everyone for the comments,
