Goto doesn't work

Questions

Goto doesn’t recognize the label:

For[j = 1, j <= 10, j++,
  For[i = 1, i <= 10, i++,
   If[i == 3 && j == 4, Goto["ab"]]
   ]];
Label["ab"];
Print[i, j]

As explained in Problem with Label in a Do loop you need to have Goto and Label inside the same CompoundExpression.

For your case each line is a separate one. Quick fix is to wrap them with ():

(
 For[j = 1, j <= 10, j++, 
    For[i = 1, i <= 10, i++, If[i == 3 && j == 4, Goto["ab"]]]];
 Label["ab"];
 Print[i, j]
)

Thanks.
