Problem with nested loops

Seems like the outer iteration variable is reset in the inner loop.
Example below.

class Bug {
static  func printCoeff(int K,int M)
$define DEBUG
    int i=0
    int j=0

    while(i<=K)
        ;print("i1=",i)
        while(j<=M)
           if i>0
              ; never get here, i is reset to 0?
              print(i, " ", j)
           endif
           ;print("i2=",i)
           j = j+1
        endwhile
        i = i+1;
    endwhile

endfunc     
}

Bugbrot {
global:
   int K = 2
   int M = 2
   Bug.printCoeff(K,M)
default:
  title = "Bug"
}

You forgot to reset j before repeating the inner loop. The first time through, i is 0 so "if i>0" is false. In subsequent iterations, j will be M+1, so the inner loop will never get executed.

Thanks, simple but I didn't see it!
