I don't know what happened ... I thought I hit Shift N ...

It's just simpler and usually clearer to write Loops (FOR, WHILE, DO) instead of chunks of DCL that don't have something like ...

  N = 1
LAB_10:
  N = N + 1
  IF (N.GE.X) THEN GOTO END_LOOP
    :
    :
  GOTO LAB10
END_LOOP:

Compare that to (in a hybrid pseudo code)...

  FOR N=1; N<X; N++
     :
     :
  END_FOR
