Displaying a variable on screen

[JFry]

I'm trying to display the player's game_score score number on screen for each individual player. I have a feeling it might be possible by using

I don't know much about console commands but this might be a way.
Does anybody know a way to achieve this effect or would it have to be done thru programming?

Generally, you can't display any dynamic value without code.
