Propeller C - Propeller Activity Board - Execute code from SD

Hello. I have heard that you can execute code on the PAB from an SD card, but after hours of scouring the internet from general ideas to very specific ideas, I have turned up with nothing. In one of the learning tutorials, the sd data one I believe, it mentions doing this later, but I never could find it. I also found that you could take byte code and cast it to a function pointer which I attempted to do here.

  sd_mount(DO, CLK, DI, CS);  FILE* fp = fopen("run.bin", "r");
  int size = 0;
  char c;
  while(fread(c, 1, 1, fp) != 0) {
    size++;
  }    
  fclose(fp);
  
  char code[size];
  
  fp = fopen("run.bin", "r");
  for(int i = 0; i < size; i++) {
    fread(c, 1, 1, fp);
    code[i] = c;
  }
  
  fclose(fp);
  
  ((void*)code)();

but failed to compile for obvious reasons. So now I ask for help from you, people of the forums. Please help me execute code from the sd card in the board.
Thank you.
