! 34: #It has been tabinated
! 35: #Now uses strict! with added feature of making everything very strict!
! 36: #about 50% through rewriting things to use split and join
! 37: #still have a lot of debugging statements that will go away after I get it to work ok(along with all the <br>'s)
! 38: #still have to rewrite the refresh tag to work right, its broken
! 39: #the whole thing is broken right now
! 40: #will rename the variables and reorder most of the script to make it more sane
! 41: #improve the general readability of the whole thing, because unlike C everyone gets to look at it, so it has to be readable
! 42: #will get to it tommorrow night as I have a calc test to "pass" yea, or something like that :0)
