Code used Pallette entrys 2 - 5 so I just looped those on each other.

REM SET OF GOSUBS FOR DIRECT VERA PALLETTE MANIPULATION
REM USES VPOKE & VPEEK
REM FOR THE OTHER ROUTINES TO WORK RELIABLY SHOULD GOSUB 45000
REM FIRST. ALSO GOSUB 45000 IS USED AT ANY TIME TO RESET
REM THE VERA PALLETTE TO DEFAULT VALUES.
REM ..
REM ...
REM WHEN THE VERA IS INITIALLY SET TO GRAPHICS MODE IT USES THE
REM DEFAULT PALLETTE BUT IF YOU USE VPEEK TO READ IT RETURNS
REM RANDOM GARBAGE... AFTER YOU VPOKE THEM IT ALL WORKS
REM AS EXPECTED.
REM .
REM ..
REM ...
REM THIS CODE DOES ABSOLUTELY NO ERROR CHECKING !!!!!!
REM IF USING R%,G% OR B% VALUES SHOULD ALWAYS BE BETWEEN
REM 0-15
REM .
REM ..
REM ...
REM WHEN USING P1 AND P2 TO POINT AT PALLETTE ENTRYS THEY SHOULD
REM ALWAYS BE BETWEEN 0 AND 255
REM I HAD ERROR CHECKING CODE WHEN WRITING THESE ROUTINES
REM BUT ERROR CHECKING TAKES CPU CYCLES.... JUST KEEP THE VALUES
REM CORRECT BEFORE CALLING.
REM .
REM ..
REM ...
REM ..
REM GOSUB 45000.. POKES IN THE DEFAULT PALLETTE VALUES
REM SHOULD BE CALLED AT INIT. AND THEN ANY TIME
REM TO RESET THE VERA TO DEFAULT VALUES
REM ..
REM GOSUB 40000.. SETS PALLETTE ENTRY P1 TO R%,G%,B%
REM ..
REM GOSUB 40100.. READS VALUES AT P1 RETURNS IN R%,G%,B%
REM ..
REM GOSUB 40200.. CHANGES THE PALLETTE COLOR P2 TO P1. BUT DIFFERENT THAN 41000
REM 41000 CHANGES IT FAST. 40200 IMPLEMENTS A FADE WITH SPEED
REM CONTROLLED BY THE VALUE OF J (BIGGER VALUE=SLOWER)
REM ACTUALLY MOST OF THE WORK DONE BY GOSUB TO 40300
REM ..
REM GOSUB 40300 FADES PALLETTE COLOR AT P1 TO R%,G%,B%
REM SPEED CONTROLLED BY THE VALUE OF J. 1 TO 10
REM IS SO FAR BEST FOR ME BUT I DIDN'T RESTRICT VALUES
REM THE BIGGER J IS.. THE SLOWER THE FADE.
REM ..
REM GOSUB 40500.. SWAPS THE PALLETTE VALUES BETWEEN P1 AND P2
REM IF AND ITS A BIG IF... I MAKE FURTHER CHANGES
REM THE NEXT ROUTINE I MAKE WILL BE TO DO THIS AS A
REM ..FADE.. USING A SIMILIAR ALGORITHM I USED IN GOSUB 40300

REM GOSUB 41000.. COPYS PALLETTE ENTRY P1 TO P2. P1 IS UNCHANGED
