Nigel had a good suggestion.

There's also the good ole' open-print-close approach, as in,

openw, unit, filename, /get_lun
print, unit, structure.name
...
free_lun, unit

Or, you could capture the output in a string and then save it later.
I use this all the time with my PRINTLOG routine,

printlog, log=log, structure.name
printlog, log=log, structure.value, format='(G9.2)'
...

and then you can do anything with the LOG array that you want. It's
just an array of strings, containing a transcript of what you printed
to it.

Good luck,
Craig

P.S. PRINTLOG is at:
