Question

I’m sitting at college making a noughts and crosses game while everyone else is learning the basics of Pascal. I can print the 2D array denoting the board into the terminal just fine, but what I want to do is update the board everytime a player adds a nought or cross, or moves their cursor around. To do this, I want to over-write the old board with the new one. Is there a way to move the console cursor up one line (Windoze console by the way), or can I clear the entire terminal in Pascal?

Thanks,

James

Ps. This is NOT homework.

Answer 1

Depending on what flavour of Pascal you are using you may be able to use gotoxy(). Typically this will be in a Pascal UNIT such as CRT, so you’ll need a USES CRT; at the start of your program, e.g.

PROGRAM main;

USES CRT;

BEGIN
  gotoxy(10, 10);
  writeln('Hello world!');
END.
