saving pointers in structures to FITS files? [message #65097]

Hi all,

I have some code that uses to a structure to store a bunch of information.
In the structure, I need to hold an array whose size will be defined (and
modified) at run-time. I figured the easiest way was just to hold a
pointer in the structure, and populate the heap variable at runtime.

However...I'd like for the structure to be persistent between idl
sessions, and I'd like the on-disk file to be fairly portable between
collaborators/idl versions. I've tried all manifestations of FITS routines
for dumping this, but mwrfits seems to just convert the data to a regular
array, and I lose the ability to modify the length of the array when i
read it back in.

Does anyone have suggestions for drop-in replacements for the FITS binary
tables? I've had problems with save files across idl versions before. Are
there better alternatives? Or is there a magic keyword to mwrfits/mrdfits
that I should be specifying? Or do I just have to suck it up and use a
save file?

cheers
chris
