..^U:ZERO. BITS: A HI-RES MIST ROUTI
NE.. BY SCOTT E. RESH.. MY G
OAL WAS TO WRITE AN ASSEMBLY.LANGUAGE PR
OGRAM THAT WOULD LOAD A.HI-RESOLUTION SC
REEN AND "MIST" IT.INTO VIEW. "MISTING"
IS A PROCESS.WHERE A SCREEN GRADUALLY C
HANGES FROM.BLANK TO A COMPLETE IMAGE.
MY.ROUTINE WILL GO FROM A BLANK SCREEN.T
O THE FINAL IMAGE IN 7 PASSES OF THE.MIS
T ALGORITHM. AFTER THE SEVENTH.PASS, TH
E LOADED SCREEN IS.TRANSFERRED TO THE "V
IEWED" SCREEN...... DURING PASS ONE,
ONLY 1 PIXEL FROM.THE LOADED SCREEN IS T
RANSFERRED TO.THE VIEWED SCREEN. PASS T
WO, TWO.PIXELS; PASS THREE, THREE PIXELS
, ETC... THE SOURCE LISTING, IN PAL F
ORMAT,.IS COMMENTED AND STRAIGHTFORWARD.
.. THIS "MIST" EFFECT EXAMPLE IS.INTE
NDED AS "FOOD FOR THOUGHT.".ASSEMBLY LAN
GUAGE PROGRAMMERS ARE.ENCOURAGED TO GO F
ARTHER. EXAMPLES:.A MULTI-COLOR VERSION
, BACKWARDS MIST.(MIST FROM COMPLETE SCR
EEN TO A BLANK.SCREEN), SMOOTH EXIT TO B
ASIC, ETC... FOR A DEMONSTRATION OF T
HE MIST.EFFECT, CHOOSE RUN IT FROM THE M
ENU,.OR JUST PRESS CMDR-R FROM THIS FILE
... THE ROUTINE WILL WORK WITH AT.LEA
ST THREE FORMATS, DOODLE!,.FLEXIDRAW AND
OCP ART STUDIO. A.DOODLE! PIC MUST HAV
E THE USUAL "DD".PREFIX; THE OTHER TWO C
AN HAVE ANY.FILENAME... SINCE THIS IS
A HI-RES MIST.ROUTINE AND NOT A MULTI-C
OLOR ROUTINE.IT WON'T WORK WITH KOALA PI
CTURES... THE DEMO DOESN'T REALLY SHO
W OFF.THE EFFECT AS WELL AS IT COULD.BEC
AUSE THE PIC WE HAVE ON THE DISK.IS SMAL
L AND ONLY USES THE TOP OF THE.SCREEN.
FOR BEST RESULTS USE THE.ROUTINE WITH A
FULL SCREEN PICTURE... THE REASON FOR
THE SMALL PICTURE.IS THAT SIDE ONE IS R
UNNING SHORT OF.DISK SPACE AND FENDER SA
YS THAT HE.FEELS ESPECIALLY VERBOSE THIS
MONTH.AND NEEDS SOME ROOM FOR DISKOVERY
... AFTER YOU SEE THE MIST EFFECT,.JU
ST PRESS A KEY AND YOU CAN SEE IT.AGAIN
OR RETURN TO LOADSTAR. BECAUSE.A SCREEN
CLEAR IN BASIC FILLS THE.SCREEN WITH SP
ACES, YOU WILL ALWAYS.SEE RED ON BLACK W
HEN YOU RUN THE.ROUTINE AGAIN. WHY RED
ON BLACK?.WELL, RED IS 2 AND BLACK IS 0,
RIGHT?.A SPACE IN HEX IS 20. THE FOREG
ROUND.TAKES THE FIRST NIBBLE AND THE.BAC
KGROUND TAKES THE SECOND NIBBLE..GENERAL
LY, OTHER THAN FOR A DEMO, YOU.WON'T BE
RE-MISTING A PICTURE... IT'S EASY TO
USE THIS ROUTINE IN.YOUR OWN BASIC PROGR
AM. JUST DO THE.FOLLOWING THREE THINGS:
.. 1. LOAD "MIST.O",8,1 OR BETTER YET,.
USE POKE147,0:SYS57812"MIST.O".
,8,1:SYS62631.. 2. PUT THE SCREEN NAME
IN A STRING. SUCH AS, A$="SCREEN NA
ME".. 3. THEN SIMPLY, SYS49152,A$..
IN THE COMING MONTHS I'M LOOKING.FORWARD
TO SHOWING YOU SOME MORE.EFFECTS THAT A
