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