I am a newbie in pascal. I'm going to write a procedure that can convert the text inputted into the menu.

ChooseOption(' Yes No ');


When Down arrow key(#80) is pressed, then it go to the "No" option and change it's colour.
Anyone can code this , it's too difficult for me. Thank you.:$
I'm using the Dev Pascal.

You are going to have to play with the crt unit. It has procedures and functions that will let you do things to the screen (clear it, move the cursor to a specific location, change colors, etc.)

Good luck.
