Hi David!

Try this:

Code:

@wafermaps = (
  "XXXX111111111X1111XXXX",
  "1X1111111X111111111X111X",
);

for $wafermap ( @wafermaps ) {
  $one = () = $wafermap =~ m/1/g;
  $ex  = () = $wafermap =~ m/X/g;

  printf("----------- $wafermap ----------\n");
  printf("one's: $one\n");
  printf("ex's : $ex\n");
}

Here is the wafermap look like in file

....XXXX1111111 11X1111XXXX....
..1X1111111X111 111111X111X..

I need help in perl code to check number of 1 (good die) and to check X for (bad die). After it read the file it should print out total number of 1 and X.

Anything it help.

Thank you in advance for your help and time.
