Creating and editing records

sinnerz92 (2)
I've been working on a little project, but I can't seem to get around one problem. I want my program to replace the first pair of '0' in the record to a new pair I will indicate in the program. I have no problems loading the record from the text file, but the program tries to replace the record something goes wrong and I'm not sure what I'm doing wrong. Not even sure if this is possible actually but any input will be greatly appreciated.

I know it's a mess, please bear with me. :)

data[a][b] This is an error when a == 32. Either change make the array larger or change the loop condition so that a < 32 always.
