Screen Effects - Philip Lock (Your Sinclair-March 88-Page 77)

[files SFX1.*]



Yawn! Have you ever realised how the way a screen is printed is so totally

boring? I mean one minute the screen's blank, then the screen's there -

sooooo boring. But wait, here is Philip Lock to the rescue with a collec-

tion of no less than 14 ways to recall a screen from memory. They include

fades, shutters, slides and colour doors. And they are very effective I

can tell you. What are you waiting for? Get typing!



METHOD

Easy as pie: all you have to do is type in the hex dump using the hex loader

(see TICK-TOCK CLOCK). Done that? Good, now save the whole lot by typing

SAVE "effects"CODE 60000,696. Now type in the little demo proggie and run

it to see an effective compendium of effects. Go for it!

 If you want to use the routines independently just load your screen into

the memory by typing LOAD ""CODE 53000, (or alternatively load the screen 

as per normal, then RANDOMIZE USR 60016 to store in memory) then consult

the table below and RANDOMIZE USR address for whatever address the routine

resides at.

 If you really like a particular routine and want to use it in your own

masterpieces, just save the routine by typing: SAVE "name"CODE address,

lenght, substituting the words for values from the table:
