Switch..case statement???

from what i understand zscript is basically the C language with built in functions, so why does it not seem to understand a switch statement?

example of code i wrote:

 
switch (best_dir) 
 {
  case 1:
  for (int n = 1 ; n<16 ; n+=4)
  {
  this_ffc->y-=4
  Waitframe();
  }
  break;
  case 2:
  for (int n = 1 ; n<16 ; n+=4)
  {
  this_ffc->x-=4
  Waitframe();
  }
  break;
  case 3:
  for (int n = 1 ; n<16 ; n+=4)
  {
  this_ffc->y+=4
  Waitframe();
  }
  break;
  case 4:
  for (int n = 1 ; n<16 ; n+=4)
  {
  this_ffc->x+=4
  Waitframe();
  }
  break;
 }

Am i useing this wrong or is it not possible to use switch
(or is it select..case, i always get confused when useing different languages 🙄 )
