Batch if statement error

Question

I am attempting to make a minesweeper in batch but i am having strange errors. When I run the file it lays 5 mines. Then it goes through the rest of the squares and checks to see how many mines are adjacent to each square. My problem is that it only senses an out put to the south-east. The south-east code is no different than the code for any other directions. This is very confusing to me. It seems like no one else has had this error. This is what an example output would be:

M 0 1 0 0
0 1 0 M 0
M 0 M 0 0
0 0 1 0 0
0 0 0 M 0

An answer would be greatly appreciated.

Your major problem is trailing spaces on lines. In a conventional set statement, any trailing spaces are included in the value assigned, and "M" and "M " are completely different things, so if you have set X=!something! then the value assigned is different from that assigned by set X=!something!.

You also have a problem where you are confusing your X with your Y. For instance, setting W is done with X and Y+1 - the same as setting N. This should be X-1 and Y.
