Rice / The Skeptic Tank Share Follow edited Oct 20, 2011 at 12:17 The Big PEEKs, POKEs, and CALLs List Compiled by Edhel Iaur, Esq. You've probably seen a lot of these before, but you may still find a useful P,P, or C that is new to you (assuming it works! : ) ). Some are for ProDOS, some are for DOS 3.3, and some are for Applesoft BASIC in general. A lot of the DOS 3.3 stuff came from Bert Kersey's DOSTalk Scrapbook. As usual, I claim no responsibility for any damage, etc. these may do. Some of the info may be less than 100% accurate; I haven't updated this in a long while. Without further ado, here's my really big PEEKs, POKEs, and CALLs and stuff list. A little more ado:As always, feel free to email/post to me questions about this stuff. MEMORY ADDRESSES $06-$09 = Free $18-$1F = Free $4E-$4F = Constantly randomly changing numbers $CE-$CF = Free $EB-$EF = Free $F9-$FF = Free $C9-$CD = Random numbers? $100-$95FF = Free $300-$3FF = Free $9600-$BFFF = DOS 3.3 $9600-$BEFF = BASIC.SYSTEM $9D5E = Routine called after RESTART is pressed $A963 = Two-byte value that is the max. value allowed w/the L parameter $AA57 = Current MAXFILES setting $AAB1 = Default MAXFILES setting $BE43 EXEC file active (status) $BE44 Input file active (status) $BE45 Output file active (status) $BE46 Prefix active (status) $BE47 Directory file being accessed (status) $BE48 End of directory data reached (status) $BE49 Index to free string space (in K) (data) $BE4A Character count for WRITE's temporary buffer (data) $BE4B Current character count during keyboard entry (data) $BE4C ASCII code of last character sent to output (used in error detection) $BE4D Number of open files (doesn't include EXECs) (data) $BE4E EXEC file is being closed (status) $BE4F DIR file is being read (status) $BE58-59 The last used A parameter $BE5A-5C The last used B parameter $BE5D-5E The last used E parameter $BE5F-60 The last used L parameter $BE61 The last used S parameter $BE62 The last used D parameter $BE63-64 The last used F parameter $BE65-66 The last used R parameter $BE67 The last used V parameter $BE68-69 The last used @ parameter $BE6A The last used T parameter $BE6B The last used number after PR# or IN# $BF00-$BFFF = ProDOS's global page $C000-$FFFF = ROM $D000-$F7FF = Applesoft BASIC $E000-$F7FF = Integer BASIC $F800-$FFFF = Hex. Language 976 = Warmstart entry 43140-43379 = DOS 3.3 commands 43380-43581 = DOS 3.3 error messages 45991-45994 = DOS 3.3 file-type codes 46010-45999 = Disk volume header (backwards) 48640 = Warmstart entry to BASIC.SYSTEM 53456-54116 = Applesoft commands and error messages PEEKS, POKES, AND CALLS Poke 32,X Set left margin of text window Poke 33,X Set width of text window Poke 34,X Set top margin of text window Poke 35,X Set bottom margin of text window Peek (36) Horizontal cursor position Peek (37) Vertical cursor position POKE PEEK(40)+PEEK(41)x+PEEK(36),32 Makes cursor either not flash or be invisible, depending on whether x is 156 or 256 Poke 50,63 INVERSE Poke 50,127 FLASH Poke 50,128 Listings and CATALOGs invisible Poke 50,255 NORMAL Poke 82,128 Cassette program will automatically RUN when loaded Peek 103 & 104 - (Two-byte number) LOMEM value POKE 109,PEEK(107):POKE 110,PEEK(108) Deletes all arrays. Lets you reDIMention any or all arrays Peek 115 & 116 - (Two-byte number) HIMEM value POKE 214,128 or 255 Makes disk program RUN when any command is issued X = PEEK (218) + PEEK (219) * 256 -- X equals line where error occured Peek 232 & 233 Two-byte value of address of shape table Peek (241) 256-SPEED Call -380 NORMAL Call -384 INVERSE Call -875 Clears entire text line Call -912 Scrolls up one line Call -958 Clears the bottom of the text screen X=PEEK(978) Determines where DOS is - if less than 157 then DOS is below normal location - computer has less than 48K memory; if 157 then DOS is at its normal 48K location; if 190 then DOS is ProDOS, not DOS 3.3; if greater than 190 then DOS is in the language card. Another source says this PEEK can show memory size if used as: PRINT (PEEK(978)+35)/4;"K" POKE 1011,224 Makes RESET reboot POKE 1010,102:POKE 1011,213:POKE 1012,112 Makes RESET RUN. Also unhooks DOS. Use CALL 1002 at beginning of program to rehook it. POKE 1013,76:POKE 1014,26:POKE 1015,252 Makes "&" move cursor up one line Peek (2040)-192 Current active slot POKE 40286,252:POKE 40287,164 Makes RESET RUN Call 42340 Locks up disk to prevent writing on it. CAUTION: BACK UP DISK BEFORE USING Poke 44467,234:Poke 44468,234:Poke 44469,234 Causes DOS 3.3 to forget to show you the disk catalog header the next time you catalog a disk Poke 44480,234:Poke 44481,234:Poke 44482,234 Causes DOS 3.3 to forget to show you the disk volume number the next time you catalog a disk POKE 44452,22:POKE 44605,21 Controls number of files displayed in CATALOG;
