ugBASIC User Manual

This example will show the generation of random value. The function used is RND(…) that generate a random number between 0 and the value gived as argument. This function will be applied to the current screen width and height, in order to print a string on the screen at random position.

 
    CLS
    
    DO 
       x = RND(SCREEN COLUMNS - 1)
       y = RND(SCREEN ROWS - 1)
       TEXT x, y, "UGBASIC AT RANDOM"
    LOOP
