Super Simple ZX81 Scrolling Example

Although I've been busy working with the ZX81 this month, it has been with my Gem Quest game. Not much to share yet there, but I am working on it. To get in something for the month, I thought I'd share an old demo program instead. Nothing super exciting for now, but will work to clean it up in August.
Since SCROLL Example is so short, I thought I'd just share here:
10 FOR X=0 TO 30 STEP .3
20 LET L=15+14*SIN X
30 PRINT TAB L;"ZX"
40 IF X>6.3 THEN SCROLL
50 NEXT X
Nothing too exciting. I like the easy to create SIN
wave. It looks decent enough. More next time!
