Text Messes Up Variables X And Y

I have a casio CFX 9850GC PLUS. I'm pretty handy with it and I'm making a Snake game.
I don't know if this forum is meant for serious use only, but the calculator has a getkey function which only comes in handy when programming games.

My problem is:
I have programmed a snake game and everything works except drawing the snake itself.
My problem is that I'm using variables x and y as coordinats for the head of the snake.
However when I want to draw his head using:

text y, x, "O"

my x and y variables are changed to floats which makes an error occur the next step.

A solution would be to replace x and y by other values. Which ones are best suited?
Also what happens with my x and y variables?
A bigger x seems to lead to a bigger x.
A bigger y seems to lead to a lower y.
I think these are graphic coordinats. How to get these right?

My graphic viewwindow setting is (1, 127, 1, 1, 63, 1) by the way.

Hehehe, don't worry. Just make yourself comfortable.

Concerning about your problem, you should use variables other the x and y. You can use A - Z and theta as your variable. Also if you want to convert a floating number to an integer, use the Int command.

I'll be moving this topic to the Programming/Development Section soon, so I'm just letting you know....
