      if((A[i] SUBSEP A[i+1] SUBSEP A[i+2]) in B) A[i]=B[A[i],A[i+1],A[i+2]]
}

In the END clause, you reference arrays A[x], and B[w,x,y] but you never define B. I assume that you intended for all of the A[w,x,y]=z statements in the BEGIN clause to define the array B[] instead of A[].

Note also that (like the elif's in the original post in this thread) the lines in red duplicate the two lines before that.

To match the elif's in the original post, shouldn't:
Code:
      if((A[i] SUBSEP A[i+1] SUBSEP A[i+2]) in B) A[i]=B[A[i],A[i+1],A[i+2]]

be:
Code:
      if((A[i] SUBSEP A[i+1] SUBSEP A[i-1]) in B) A[i]=B[A[i],A[i+1],A[i-1]]
