Chat GPT gave me this routine

I've asked the AI to code a loop so I can increase the size of a sprite and at the same time its 'speed' like a racing game with perspective.
The AI Gave me this

idx = 1
MAXIDX = 512

' the loop starts here, I'm using a timer currently
 if idx < MAXIDX then
 
   for k = 1 to abs(MAXIDX/2 - idx)/(MAXIDX/2)+1
     idx = idx * 1.5
   next k

 end if


Print "El valor de idx es: "; idx



It works, I don't know what that ABS( part does, but it works.

ABS is absolute value, i. e. changes a negative to a positive number.  It insures that neither the size or the velocity of the sprite is negative.
