fixed main for fancier input
deleted extraneous x
prettied up output some more
added reset codemap.  slows everything down. should change later.
finished up main again (for now)
made main stop when it reached end of file
fixed bug where input would be cast to character. totally undesireable. ints only except for output
fixed in function
prettied up input some more. still not perfect
completed loop for a second time. not likely to work but we'll see
proceeding to test loops
in exec-instruction: added debug println which highlighted the problem.  Apparently index was being changed to a function
seemed to have fixed incrementing problems.
corrected minus but still not working
