SWISS SCROLL

by Rick O'Neill



Actually, Rick O'Neill isn't from Switzerland, and neither is his

scroller. They both live in Scotland, and a good thing too.



You may remember Antony Purvis's message scroller from, oooh, way back

when. Well, this is the same sort of thing, only different. It's

similar in that it scrolls messages, and that the messages are really

big, being formed in the attribute file. The difference, though, is

that these messages are BIG. Yup, they fill up the whole screen. Also,

they're not interrupt driven so, while not being quite as versatile as

the first one, the program is a touch shorter and easier to use.



The "getting it in" routine is the same as usual - type in the Basic

and save it onto a tape. Then, using the Hex Loader, type in the Hex

and save that after the Basic. Run the program and you'll be given a

demo.



To make use of the routine in your own programs you'll need to type

what you want scrolled into a REM statement at the beginning of the

program. You can use all the usual characters and also colour control

codes (there were some quite fetching ones in the demo, but sadly they

didn't print out). The POKE SCRL+1,LINE and RANDOMIZE USR SCRL, where

SCRL is the start address of the routine and LINE is between 0 and 255

(the number of the REM line).
