SET /A and multidimensional array.

This works as expected in versions <= 22. It fails in versions 23 and 24.

v:\> setarray a[2,2]

v:\> set a[0,0]=1

v:\> set /a a[0,0]+=10
0
TCC: Syntax error "0]+10"

Here's v22.

g:\tc22> setarray a[2,2]

g:\tc22> set a[0,0]=1

g:\tc22> set /a a[0,0]+=10
11

g:\tc22> echo %a[0,0]
11

You're running into some more CMD compatibility issues, where CMD thinks a comma indicates a new argument, or sometimes the last expression in a group.

Don't use array variables with SET /A.
