C H E R.. BY FENDER TUCKER AND GERRY A

ABOUT THE C64 IS THAT IT ALLOWS THE.INDI

OUT. UNLIKE SOME OF THE.OTHER POPULAR C
OMPUTERS, THERE ARE.FEW 'CONVENTIONS' FO
R MENUS, SCREEN.LAYOUTS, DIALOG BOXES, E
TC. AS.EDITOR, I LIKE TO SEE SOME NEW,
EVEN.ODDBALL, METHOD OF PRESENTING A.PRO
GRAM COME ACROSS MY DESK, AND I.USUALLY
LET IT REMAIN THE WAY THE.AUTHOR WROTE I
T... THERE ARE A FEW EXCEPTIONS...
THERE IS ONE CONVENTION WE WOULD.LIKE T
O SEE IN JUST ABOUT ALL.LOADSTAR PROGRAM
S AND THAT IS EASY.ACCESS TO A HELP SCRE
EN. A LOADSTAR.USER SHOULD NEVER BE MOR
E THAN A.KEYPRESS AWAY FROM A LIST OF TH
E.COMMANDS AVAILABLE TO HIM... THIS I
S THE RAISON D'ETRE FOR.SCREEN SWITCHER,
A PROGRAM WRITTEN BY.A SUB-AVERAGE ML P
ROGRAMMER (MOI).THAT, NONETHELESS, IS RE
AL HANDY..ALL YOU HAVE TO DO IS USE A FE
W SYS.COMMANDS TO SAVE YOUR CURRENT SCRE
EN,.DISPLAY YOUR HELP SCREEN, AND BRING.
THE ORIGINAL SCREEN BACK WHEN THE.USER H
AS BEEN HELPED... SCREEN SWITCHER IS
ACTUALLY A.DEMO OF THE ML MODULE. ALL Y
OU.REALLY NEED FOR YOUR OWN PROGRAMS IS.
THE FILE "SS" WHICH IS A 142 BYTE ML.ROU
TINE WHICH RESIDES IN THE CASSETTE.BUFFE
R. THIS DEMO WAS ORIGINALLY A.CLEVER KA
LEIDOSCOPIC GEM BY MASTER.PROGRAMMER GER
RY ABEAR THAT I.MODIFIED TO SHOW HOW TO
USE THE SS.MODULE. HE CALLS IT COFFEE B
REAK.BECAUSE IT'S AS REFRESHING AS ONE..
. AFTER YOU HAVE RUN AND ENJOYED.SCRE
EN SWITCHER AS MUCH AS YOU WISH.PRESS RU
N/STOP AND LIST THE PROGRAM..THE FIRST L
INE IS A HANDY BLOAD.COMMAND THAT I HAD
NEVER SEEN BEFORE.UNTIL JIM HILTY, AN OF
T-PUBLISHED.LOADSTAR AUTHOR, SHOWED IT T
O ME.. IF YOU WANT TO LOAD A FILE WIT
H.THE ,8,1 SUFFIX AND WOULD RATHER IT.NO
T SEND THE PROGRAM COUNTER BACK TO.THE B
EGINNING OF THE PROGRAM, USE.THIS SEQUEN
CE:.. POKE147,0. SYS57812"FILENAME",
8,1. SYS62631..SO NOW YOU (AND I) CAN
FORGET ALL OF.THOSE IFA=0THENA=1:LOAD...
. ETC..COMMANDS THAT SO MANY PROGRAMS ST
ART.OFF WITH. WHY DIDN'T COMMODORE TELL
.US ABOUT THIS YEARS AGO? OR, WHY.DIDN'
T I LEARN ABOUT THIS YEARS AGO?.. BUT
I DIGRESS... THE FIRST THING THE DEM
O DOES IS.PRINT TO THE SCREEN WHAT WILL
BECOME.THE 'HELP SCREEN'. IN THE BYTES.
FEATURE OF LOADSTAR #49 I EXPLAINED.IN D
ETAIL ABOUT SAVING SCREENS TO.DISK, SO Y
OU DON'T HAVE TO PRINT YOUR.HELP SCREEN
TO THE SCREEN, YOU CAN.LOAD IT IN FROM D
ISK IF YOU HAVE.CREATED AND SAVED ONE PR
EVIOUSLY..SCREEN SWITCHER WILL ALLOW YOU
TO.BRING UP THE HELP SCREEN IMMEDIATELY
,.ONCE YOU HAVE IT MEMORIZED... THE C
OMMAND FOR MEMORIZING THE.HELP SCREEN IS
SYS 886 IF YOU WANT IT.SAVED AS SCREEN
ONE, OR SYS 928 IF.YOU WANT IT SAVED AS
SCREEN TWO.... WHEN I FIRST WROTE SCR
EEN.SWITCHER I ONLY GAVE IT THE.CAPABILI
TY OF SAVING ONE SCREEN, BUT.I SOON REAL
IZED THAT ONE IS NOT.ENOUGH. YOU NEED T
O BE ABLE TO SAVE.THE CURRENT SCREEN AS
WELL AS THE.HELP SCREEN... LINE 170 S
AVES THE DISPLAYED.SCREEN AS THE HELP SC
REEN, AND THEN.GERRY'S PYROTECHNICS TAKE
OVER FOR.THE NEXT THIRTY OR SO LINES.
COFFEE.BREAK IS ACTUALLY A TRIPLE-NESTED
.LOOP. LINE 400 IS THE LINE THAT.CHECKS
FOR A PRESS OF THE SPACE BAR..IF YOU PR
ESS IT THE SUBROUTINE AT.LINE 630 IS CAL
LED. THIS SUBROUTINE.SHOWS ONE WAY OF U
SING SCREEN.SWITCHER.. REMEMBER THAT
THE HELP SCREEN IS.STORED AS SCREEN ONE.
SYS 928 SAVES.THE CURRENT SCREEN AS SC
REEN TWO AND.THEN SYS 907 BRINGS BACK SC
REEN ONE.INSTANTANEOUSLY (FOR ALL PRACTI
CAL.PURPOSES). THEN, WHEN THE USER.PRES
SES A KEY, THE SYS 949 IN LINE.670 TAKES
