The problem is when I use AOBSwap or StringSwap they only replace 1 but they don't replace the rest. These function should search for the values that should be replaced once they are found, they get replaced.
These 2 functions are in memlib.h. If you can only help me with 1 function I would be really happy, I am trying to fix them for about 1-3 hours..

Then how about you do a repeated check for that?

while( ResultsFound )
replaceStuff();
