..^U:HACKER... TWO IN ONE.
BY. NICK PECK
... IF YOU READ THE LATEST IBM AND.MAC
INTOSH MAGAZINES YOU'LL FIND THAT.THE HI
GH-PRICED COMPUTER FIELD IS.FASCINATED W
ITH "MULTI-TASKING." THE.IDEA OF ONE CO
MPUTER DOING MORE THAN.ONE JOB AT A TIME
HAS COME OF AGE..NOW, THANKS TO ACE UTI
LITY MAN NICK.PECK, WE CAN ALL ENJOY A F
ORM OF.MULTI-TASKING ON THE COMMODORE 64
... TWO IN ONE IS AN INTERRUPT-DRIVEN.
UTILITY THAT YOU LOAD INTO HIGH RAM.WITH
A SMALL BASIC PROGRAM. IT.REPLACES THE
FAMILIAR BASIC PROMPT,."READY" WITH THE
WORDS "ONE" OR."TWO," TELLING YOU WHICH
COMPUTER.YOU'RE WORKING WITH. THAT'S R
IGHT:.TWO IN ONE MAKES YOUR TRUSTY C64.B
EHAVE AS IF IT WERE TWO SEPARATE.COMPUTE
RS. EACH "COMPUTER" HAS ITS.OWN SECTION
OF MEMORY AND IS DISTINCT.FROM THE OTHE
R. ANY PROGRAM YOU WORK.ON IN "ONE" WIL
L BE UNAFFECTED BY THE.PROGRAM YOU'RE WO
RKING ON IN "TWO.".. HERE'S HOW TO USE
IT. FIRST, LOAD.AND RUN THE BASIC PROG
RAM "TWO IN.ONE". PRESSING CTRL-F5 FLIP
S BETWEEN.THE TWO SECTIONS, OR TASKS. N
EXT,.CHOOSE THE AMOUNT OF MEMORY USED BY
.EACH SECTION BY PRESSING EITHER THE."+"
OR "-" KEYS. IF ONE OF THE TWO.PROGRAM
S YOU WANT TO WORK WITH IS.EXTRA LARGE,
MAKE ONE OF THE SECTIONS.LARGE ENOUGH TO
HOLD IT -- JUST MAKE.SURE YOU LOAD THE
LARGE PROGRAM INTO.THE LARGE SECTION...
WHEN YOU PRESS RETURN YOU'LL BE IN.SEC
TION ONE, WHICH HAS A BLACK.BACKGROUND A
ND LIGHT GREEN.CHARACTERS. YOU'LL ALSO
SEE THE.PROMPT "ONE." INSTEAD OF "READY"
..NOW PRESS THE CTRL-F5 COMBINATION..VOI
LA! THE SCREEN CHANGES TO THE.FAMILIAR
BLUE ON BLUE AND THE PROMPT.NOW READS "T
WO.". YOU'RE IN THE.SECOND SECTION. NO
TICE THAT CTRL-F5.TOGGLES BACK AND FORTH
BETWEEN THE.TWO SECTIONS... LET'S TES
T IT OUT. GO TO SECTION.ONE AND LOAD IN
A BASIC PROGRAM,.PREFERABLY ONE THAT PR
INTS THINGS TO.THE SCREEN. RUN IT AND S
EE THAT IT.WORKS NORMALLY. IT'S AS IF N
OTHING.HAS CHANGED... NOW PRESS CTRL-F
5 AND WE'RE IN.SECTION TWO WITH THE BLUE
SCREEN AND.THE PROMPT, "TWO.". LOAD IN
ANOTHER.PROGRAM AND RUN IT. IT, TOO, W
ORKS.AS IT SHOULD. NOW HERE'S THE MAGIC
AL.PART. WHEN WE PRESS CTRL-F5 WE'RE.BA
CK IN SECTION ONE WITH THE FIRST.PROGRAM
AND IT'S STILL RUNNING..PRESS CTRL-F5 A
GAIN AND WE'RE BACK IN.THE SECOND PROGRA
M AND IT'S STILL.RUNNING... BUT BEFORE
YOU GO TELLING YOUR.FRIENDS ABOUT YOUR
MULTI-TASKING.COMPUTER WE NEED TO INTERJ
ECT A.DISCLAIMER AT THIS POINT. TRUE.MU
LTI-TASKING REQUIRES TWO CPUS AND.OPERAT
ING SYSTEMS AND OF COURSE THE.C64 ONLY H
AS ONE. TWO IN ONE ALLOWS.TWO SEPARATE
PROGRAMS TO RESIDE IN.MEMORY AT THE SAME
TIME, BUT ONLY ONE.IS REALLY RUNNING AT
ANY PARTICULAR.TIME. IF ONE OF YOUR PR
OGRAMS IS.COUNTING AND PRINTING THE RESU
LTS TO.THE SCREEN, YOU CAN SEE THAT WHEN
YOU.RETURN TO THAT PROGRAM, IT TAKES UP
.WHERE IT LEFT OFF WHEN YOU EXITED.FROM
THAT SECTION... TWO IN ONE IS MORE THA
N A PARLOR.TRICK, HOWEVER. WHEN REVISIN
G A.PROGRAM, PROGRAMMERS OFTEN NEED TO.C
HECK THE UNREVISED VERSION FOR.COMPARISO
N. NO PROBLEM -- IF YOU.HAVE TWO IN ONE
. JUST KEEP THE.UNREVISED VERSION IN SE
CTION TWO AND.REFER TO IT WHEN YOU NEED
TO. OR.PERHAPS YOU HAVE A UTILITY ON DI
SK.THAT YOU NEED TO ACCESS PERIODICALLY.
AS YOU WORK ON ANOTHER PROGRAM? FILE.IT
AWAY IN SECTION TWO. A REAL HANDY.THIN
G TO HAVE AVAILABLE WHEN.PROGRAMMING IS
A SMALL WORD PROCESSOR.FOR TAKING NOTES.
YOU MAY WANT TO.KEEP THE WORD PROCESSO
R IN SECTION.ONE WHICH IS THE "NORMAL" B
ASIC AREA.BEGINNING AT $0800 (2048) AND
USE.SECTION TWO FOR YOUR OTHER PROGRAM..
. THERE ARE UNDOUBTEDLY OTHER.APPLICAT
IONS OF A CLEVER PROGRAM LIKE.THIS. SEE
WHAT YOU CAN COME UP WITH... A FINAL
NOTE: IF YOU ENTER RUN OR.SOME OTHER BA
SIC COMMAND AND THE.COMPUTER RESPONDS WI
TH THE DREADED.SYNTAX ERROR MESSAGE, DON
'T PANIC..IN THE IMMEDIATE MODE ENTER.PO
KEPEEK(44)*256+PEEK(43)-1,0 AND ALL.SHOU
LD BE WELL... ALSO, BECAUSE OF THE NAT
URE OF.THIS PROGRAM, YOU MUST REBOOT TO.
