Doesn't write into the file

[G33k]

I use FPS [ this one: FPS – About ] for pascal. I write this code, but it doesn't put number into the file, what's the problem?

program lalala;
  var prad : text;
begin
  assign(prad, 'C:\Users\Tomas\Desktop\numbers.txt'); rewrite(prad);
  write(prad, 1)
end.

You haven't closed prad. Also, it's likely that you are writing the binary value 1, so you may have to check it using a hex editor.

Yes, you are right, I have to close it then it works, thank you.
