TIONS 0 THROUGH 255..0 AND 1 - VERY IMPO
RTANT FOR I/O AND.SWITCHING THE ROMS IN
AND OUT. BITS.0, 1 AND 2 OF LOCATION 1
ARE THE.OPERATIVE SWITCHES. HERE'S WHAT
.THESE BITS DO:.. BIT.. 0 ON BASIC R
OM AT $A000 (40960). OFF RAM AT $A0
00.. 1 ON KERNAL ROM AT $E000 (57344
). OFF RAM AT $E000.. 2 ON I/O
AT $D000 (53248). OFF CHARACTER ROM
AT $D000..2 - UNUSED BY BASIC. THIS IS
A.FAVORITE PLACE TO STORE A VALUE.BETWE
EN 0 AND 255. BE CAREFUL.THOUGH, IT'S U
SED BY A LOT OF ML.ROUTINES...19 - DEFAU
LT VALUE IS 0. IF YOU POKE.A 64 HERE, T
HE ? IS SUPPRESSED FROM.AN INPUT STATEME
NT. BE SURE TO POKE.A 0 BACK IN AFTER Y
OU GET YOUR INPUT.OR YOU'LL HAVE CURSOR
PROBLEMS WITH.THE BASIC SCREEN EDITOR.
SINCE.LOADSTAR IS NOT A FAN OF THE INPUT
.STATEMENT ANYWAY, MY ADVICE IS TO USE.T
HIS FOR YOUR OWN PROGRAMS, IF YOU.WANT,
BUT NOT FOR PROGRAMS TO BE USED.BY THE G
ENERAL PUBLIC....43 AND 44 - POINTERS TO
THE START OF.BASIC TEXT. DEFAULT IS 01
AND 08 OR.2049 DECIMAL. TO MOVE THE ST
ART OF.BASIC TEXT UP TO $1001 (4097) YOU
.NEED TO POKE 44,10:POKE 4096,0 IN A.BOO
T PROGRAM. THIS ALLOWS ENOUGH.ROOM FOR
A FONT TO BE LOADED AT.$0800. THESE LOC
ATIONS ARE ALSO.TEMPORARILY CHANGED WHEN
APPENDING.BASIC PROGRAMS. IF YOU EVER
GET A."SYNTAX ERROR" WHEN ENTERING A SIM
PLE.BASIC COMMAND LIKE RUN, YOU PROBABLY
.NEED TO POKE2048,0. IF YOU'VE MOVED.BA
SIC UP, THEN POKE A 0 INTO THE.VALUE RET
URNED BY PEEK(44)*256.......45 AND 46 -
START OF VARIABLES (SOV).OR, IN ANOTHER
SENSE, END OF PROGRAM..THESE BYTES CHANG
E AS YOU MODIFY YOUR.PROGRAM. USED IN A
PPENDING ALSO...51 AND 52, 55 AND 56 - U
SUALLY ONLY.THE HI-BYTES (52 AND 56) NEE
D TO BE.CHANGED TO LOWER THE TOP OF BASI
C..THE DEFAULT VALUE FOR 52 AND 56 IS.16
0 WHICH PLACES THE TOP OF BASIC.AREA AT
$A000 (40960). 160X256=40960..TO FREE U
P ROOM FOR DATA, ML ROUTINES.OR WHATEVER
, POKE 52 AND 56 WITH A.LOWER NUMBER....
..197 AND 203 - IN "MAPPING THE C64".THE
RE IS A TABLE OF THE VALUES FOUND.IN THE
SE LOCATIONS DEPENDING ON WHICH.KEY HAS
BEEN PRESSED. THEY ARE THE.SAME FOR BOT
H LOCATIONS EXCEPT THAT.197 SHOWS THE LA
ST KEY PRESSED, WHILE.203 SHOWS THE CURR
ENT KEY PRESSED..THESE LOCATIONS ARE HAN
DY FOR.CHECKING FOR A KEYPRESS...IN THE
IMMEDIATE MODE ENTER THIS.COMMAND,..
FORI=0TO9000:?PEEK(197);:NEXT..AND PRESS
RETURN. A BUNCH OF 64'S.WILL BE PRINTE
D ON THE SCREEN.... THEN PRESS ANY KE
Y AND SEE WHAT.NUMBER IS PRINTED. FOR I
NSTANCE, IF.YOU PRESS THE SPACE BAR THE
NUMBER 60.WILL BE PRINTED. THEREFORE..
10 IF PEEK (197) = 60 THEN......IS THE
SAME AS.. 10 GET A$: IF A$ = " " THEN..
....IF NO KEY IS PRESSED, BOTH 197 AND.2
03 WILL CONTAIN A 64...THIS CHECKS ONLY
FOR WHICH KEY IS.PRESSED. THE SHIFT, CO
NTROL AND LOGO.KEYS ARE NOT PART OF THE
KEYBOARD.MATRIX SO SHIFT-SPACE WILL GIVE
THE.SAME VALUE AS UNSHIFTED-SPACE..198
- NUMBER OF CHARACTERS IN THE.KEYBOARD B
UFFER QUEUE. DEFAULT IS.10. TO MAKE SU
RE THAT A PREVIOUS.KEYPRESS IS NOT LURKI
NG IN THE BUFFER.IT'S GOOD PROGRAMMING P
RACTICE TO.POKE 198,0 BEFORE ANY GET STA
TEMENT..EVEN MORE USEFUL IS TO POKE SOME
.BASIC TOKENS INTO THE KEYBOARD BUFFER.A
T 631 AND THEN POKE THE NUMBER OF.TOKENS
INTO 198. WHEN THE PROGRAM.ENDS THE CO
MMANDS YOU POKED WILL BE.EXECUTED EVEN T
HOUGH THE PROGRAM IS.OVER AND NO KEYS AR
E PRESSED! THIS.IS KNOWN AS THE DYNAMIC
KEYBOARD.TECHNIQUE AND IS HANDY FOR CAU
SING.ONE PROGRAM TO LOAD AND RUN ANOTHER
..JUST ABOUT ALL OF OUR BOOT PROGRAMS.US
E THIS METHOD. CHECK 'EM OUT...199 - A
QUICK WAY TO TELL IF YOU ARE.IN THE REVE
RSED MODE. 0 = NO. 1 =.YES. YOU CAN P
OKE OR PEEK THIS.LOCATION FROM WITHIN YO
UR PROGRAM...212 - AN EASY WAY TO GET OU
T OF THE.QUOTE MODE FROM WITHIN A PROGRA
M..0 = NO. IF YOU WANT TO PRINT A.QUOTE
MARK ON THE SCREEN BUT DON'T.WANT THE U
SER TO BE IN THE QUOTE.MODE, JUST POKE 2
12,0 AFTERWARDS...214 - THE BEST WAY (IN
MY OPINION) TO.POSITION YOUR CURSOR IN
A PROGRAM IS.TO POKE THE ROW YOU WANT TH
E CURSOR.ON (MINUS 2) INTO 214. FOR INS
TANCE,.POKE 214,12:PRINT WILL POSITION T
HE.CURSOR ON THE 14TH ROW. USE TAB OR.S
PC TO SET THE CURSOR Y POSITION..217 THR
OUGH 242 - SCREEN LINE LINK.TABLE. THES
E ARE TWENTY-FIVE BYTES.(CORRESPONDING T
O THE 25 SCREEN ROWS).THAT NEED TO BE MA
NIPULATED WHENEVER.YOU PRINT SOMETHING I
N THE FAR RIGHT.COLUMN. YOU'LL NOTICE T
HAT YOU ARE.HAVING A HECK OF A TIME GETT
ING.SUCCEEDING TEXT TO PRINT ON THE.CORR
ECT LINE. IF YOU HAVE THIS.PROBLEM, DO
THIS:.. 200 FOR I = 217 TO 242: POKE I,.
PEEK(I) OR 128:NEXT..AND THE SCREE
N WILL FORMAT CORRECTLY..TECHNICALLY, YO
U ONLY NEED TO DO THIS.FOR THE OFFENDING
LINE BUT IT'S QUICK.ENOUGH TO FIX ALL T
HE LINKS AT ONCE.IN A FOR-NEXT LOOP...25
1 THROUGH 254 - THESE ARE FAVORITE.FREE
ZERO-PAGE BYTES FOR ML.PROGRAMMERS. SOM
E OF THE ADDRESSING.MODES REQUIRE THAT A
DDRESSES BE IN.ZERO PAGE AND SINCE ADDRE
SSES ARE TWO.BYTES LONG, HAVING FOUR IN
A ROW IS.INDEED HANDY... BY STUDYING
SHELDON LEEMON'S BOOK.YOU'LL FIND MANY M
ORE INTERESTING.LOCATIONS TO PLAY AROUND
