[Nothinman]

You're going to have to post a link to the source somewhere on the 'net, the forums interpreted some of your code as formatting codes.

 

[Beerinator]

there i fixed it

 

[HigherGround]

I don't have a DOS compiler, however some errors are easy to spot, like this one ...

#define MAX 45; <- remove ';'

 

[Beerinator]

Yeah I saw that right away when I reposted it on the forum, that made LIFE SOO MUCH EASIER
knocked errors down to like 1.
Thanks anyways.

<< Knocked the errors down to like 1? I don't think so. There were tons of errors, mostly because you just didn't indexed an element of the array, you were trying to compare the actual array itself (which is a pointer) to another integral type. Anyway, here's the fixed code. I added "FIXED" comments where I made a change.
>>



Those are phantom errors caused by the page parsers on this forum, basically all [ i ]s get swallowed, which in turn converts the proceeding text format into italic. I was hoping that people who looked at the original post would realize that, i guess i was mistaken.
