Everyone seems to be chiming in with their opinions and they are all valid.
Determining where to spend your effort is difficult, especially if you don't
have much experience with IDL and you don't have intimate knowledge of the
file format. You can really help your cause if you post a snippet of your
file since some of the experienced IDL'ers can give you their opinion on the
level of effort needed to parse a record in IDL.
If you decide to go the C++ route I would suggest coding a wrapper function
in C++ to interface your code to IDL as an dynamically loadable module (aka
dlm). I know you don't have much experience with IDL. I am hoping you have
some with C/C++? As a novice C/C++ coder I have written a number of simple
.dlms. If you have experience with C/C++ you should be well on your way.
How simple is it to use the C++ code? Do you just pass the function a file
name and it returns a struct or do you pass it a record as a char array and
it returns the parsed record in a struct? The simpler to use, the simpler
to code into a dlm.
Also, if you go the dlm route I strongly suggest picking up a copy of Ronn
Kling's book "Calling C from IDL" available from his website
www.kilvarock.com.
I could probably work up an example of a dlm which returns a structure to
IDL if you are interested.
