So I have to replace all of my calls to IO functions such as linein()
and charin() with a 'parse pull somevariable' instruction? Then use
'somevariable' in the expression in place of linein().

It seems a lot easier to just replace the calls to linein() with
calls to linein('\temp\tempjunk') and just use tempoarary files.
Besides, I would have to re-do the logic of my program since I was
already using a stack. I would have to check after each 'parse pull'
to see if I had the re-directed STDIN or if I had stack data.
