Conditional break not allowed

[tueda]

Conditional break from a switch construction, which would be expected to work in almost any computer language that has a switch construction, doesn't work:

S x;
L F = 1;
$x = 1;
switch $x;
  case 1;
    if (count(x,1));
      break;
    endif;
endswitch;
.end
