I probably can't answer this - but can you use a C style address pointer
to pass a local variable from the math function back up to the file
naming function? By using address pointers you might be able to free up
memory that a global variable would otherwise use.

If that doesn't make sense, how about writing a second text file by
reading the first? Just use the original output as temporary disk
storage until the final text file is written kinda thing.
