up and away animation for zx81. How to improve?

[Crayon21]

so this is the animation I did, using a program I made myself. I have two. the first is Sprite move which is a simple 8 lines of BASIC allowing you to make an object and move it using z and x and c
here, a simple animation is done of a man and he goes up the elevator.
use either z or x to make an image appear, v to isolate or c to move up or down (I may have that backwards)
Whatever games you make using this, all I ask is proper credit. thanks
quite proud of myself. All of this in 1k too

Why the FOR ... loop?

[Crayon21]

I wanted a way for the animation to loop continuously without the need to run constantly.
I'm still working the kinks out
