I need someone to look over this loop routine that I made for myself which 
uses the DETECT library from ZLIB, and it will store the Address outputted 
from that Library to a place in RAM, increase that RAM pointer to store the 
progs found sequentially, then increase the Var that tells how many progs 
were found once it leaves the routine. Although, I seems to not be working 
because this was the newest thing I included in my prog and it crashed. I 
could use some help here please, I've included the I/O for that SOS library 
below for you to reference to. Can someone help me find out whats wrong, 
thanks... =)
