─OCUMENTATION FOR ┴RC-╙DA V4.6 ╫RITTEN ┬Y ┬. ═ARK ╥HODES
==============================================================================
╟REETINGS TO ┴LL! ├HECK OUT THE NEW GRAPHICS!
╘HIS PROGRAM ALLOWS YOU TO CONVERT A FILE, WHICH IS IN ┴╥├ FORMAT, INTO AN
╙ELF ─E-┴RCING FILE! ╔T ALSO CAN MAKE AN ╙─┴ FILE BACK INTO AN ┴╥├ FILE!
╬O OTHER ╨╟═ (THAT ╔ KNOW OF) DOES THAT! ╔T FURTHER CAN WHITTLE LARGE ┴╥├
FILES INTO ╙─┴ABLE SIZE CHUNKS, AND LETS YOU ANALYZE YOUR UNPROTECTED DISKS,
THEIR FILE CHAINS FOR BAD (OR OVERLAPPING TRACK AND SECTOR POINTERS)!
╓ERSION 4.6 FIXES SOME BUGS IN THE WHITTLE OPTION AND DETECTS THE TRAILING
ZERO BLOCK PROBLEM AND FIXES IT. ╘HIS ALLOWS YOU TO MAKE ┴╥├S WITH THAT
PROBLEM INTO ╙─┴'S.
╬O ═╧╥┼ NEED TO CLEAN UP! ╘HE 8 ┬LOCK PROBLEM HAS BEEN ╙╧╠╓┼─! (V4.0)
╨LEASE POST ANY COMMENTS ON ╤-╠INK IN THE ╘ELECOMMUNICATIONS/╒TILITIES SECTION
BY SELECTING THIS FILE AND HITTING ╞7.
╧R LEAVE ┼-═AIL ON ╤-╠INK TO '┬═ARK'.
===============================================================================
4.6 ╓ERSION ╬OTES
===============================================================================
╘HE ╫)HITTLE OPTION (ADDED IN V4.5) HAD BUGS THAT HAVE BEEN CORRECTED. ╔T
WOULD NOT DIVIDE LARGE ┴╥├S PROPERLY. ╔'VE DONE EXTENSIVE TESTING, AND AS FAR
AS ╔ KNOW IT WORKS PROPERLY NOW.
╞EEDBACK ON A PROBLEM WITH ╫)HITTLE LED ME TO DISCOVER A PROBLEM WITH ├HRIS
╙MEETS ╙─┴ MACHINE LANGUAGE. ┴LTHOUGH NATIVE ┴╥├ CAN DISOLVE A FILE WITH THIS
PROBLEM, THE ╙─┴ MACHINE LANGUAGE (FOR THE 64) ├┴╬ ╬╧╘! ╔ CALL THIS THE
╘╥┴╔╠╔╬╟ ┌┼╥╧ ┬╠╧├╦ ╨╥╧┬╠┼═ (╘┌┬╨). ╔ HAVE GIVEN V4.6 THE ABILITY TO RECOGNIZE
AN OPTIONALLY CORRECT ╘┌┬╨S SO THAT THE ┴╥├ FILE BECOMES ╙─┴'ABLE. ╘HIS
ABILITY IS BUILT IN TO THE ╫)HITTLE AND ┬)ROWSE (ARC FILE) OPTIONS.
╫ITHOUT GOING INTO TOO MUCH DETAIL, THE PROBLEM OCCURS LIKE THIS. ╔F ANY OF
THE FILES WITHIN AN ┴╥├ FILE HAPPEN TO END SO THAT THEY FIT ┼╪┴├╘╠┘ INTO A
SECTOR, ├┬═ ─╧╙ ADDS ANOTHER ╒╬╬┼├┼╙╙┴╥┘ SECTOR OF ALL ZEROES (BYTES 3-256)
ONTO THAT FILE! ╘HE ┴╥├ FILE THEN HAS A USELESS BLOCK WHICH JUST TAKES UP
ROOM
AND ╨╥┼╓┼╬╘╙ THAT ┴╥├ FILE FROM BEING CONVERTED TO AN ╙─┴! ╓ERSION 4.6 WILL
DETECT THIS PROBLEM AND ALLOW YOU TO OPTIONALLY FIX THIS PROBLEM EVEN IF IT
OCCURS IN MULTIPLE TIMES WITHIN THE SAME ┴╥├. ╔F YOU DO DECIDE TO FIX ANY OF
THE FILES WITHIN THE ┴╥├, ┘╧╒ ╙╚╧╒╠─ ╓┴╠╔─┴╘┼ ╘╚┴╘ ─╔╙╦ WHEN YOU ARE GIVEN THE
OPTION. ╔F YOU DON'T VALIDATE, THEN YOU WILL LOSE THE USE OF 1 SECTOR FOR
EVERY FILE FIXED. ─ETECTION OF ╘┌┬╨S WILL ABORT A ╫)HITTLE IN PROGRESS AT THE
NORMAL WHITTLE CUTOFF POINT. ╔ RECOMMEND ┬)ROWSING THE ┴╥├ AND FIXING ANY ╘┌┬╨
FILES WITHIN IT ┬┼╞╧╥┼ ╫)HITTLING OF ├)ONVERTING IT TO AN ╙─┴.
╞OR YOU TECHNICAL TYPES, IF YOU WANT TO TRY FIXING THE ╘┌┬╨ YOURSELF, REMEMBER
THAT THE BYTES IN THE ┴╥├ FILE HEADER, FOR ┼┴├╚ ╘┌┬╨ FILE, WHICH GIVE THE
LENGTH OF THAT FILE IN ┴╥├'ED FORM MUST BE ADJUSTED TO REFLECT THE NEW FILE
LENGTH AFTER THE OFFENDING ╘┌┬ HAS BEEN REMOVED FROM THE FILE CHAIN (AS WELL AS
CORRECTING THE LENGTH IN THE DIRECTORY FOR THE ENTIRE ┴╥├ AND VALIDATING THE
DISK TO RECOVER THE USE OF THE NOW UNUSED ╘┌┬S). ╔ THINK YOU'LL AGREE IT IS
EASIER TO LET ╓ERSION 4.6 DO IT FOR YOU.
╘HE ODDS OF GETTING A ╘┌┬╨ ARE 1 IN 254 FOR ┼┴├╚ FILE WITHIN AN ┴╥├!
╘HE SYMPTOM OF AN ╙─┴ WITH A ╘┌┬╨ IS THAT IT WILL JUST STOP ─E-┴RCING WHEN
IT ENCOUNTERS THE ╘┌┬. ╥EMEMBER THAT IF YOU HAVE AN ╙─┴ WITH THIS PROBLEM, YOU
CAN ═)┴╦┼ IT TO AN ┴╥├, FIX THE PROBLEM WITH ┬)ROWSE ┴╥├ AND THEN ├)╧╬╓┼╥╘ IT
BACK TO AN ╙─┴!
╔ KNOW OF NO OTHER PROGRAM WHICH DETECTS AND FIXES THE ╘┌┬╨.
===============================================================================
4.1 THRU 4.5 ╓ERSION ╬OTES
===============================================================================
╘HE ╫)HITTLE---┴╥├--TO--╙─┴ ╙IZE OPTION HAS BEEN ADDED. ╘HIS ALLOWS SINGLE
DRIVE USERS TO ─E-┴╥├ FILES THAT THEY WOULD NORMALLY BE UNABLE TO BECAUSE THE
┴╥├'ED AND DE-┴╥├'ED FILES WOULD BE TO BIG TO FIT ON THE SAME DISK! ╫)HITTLE
EXAMINES THE ┴╥├ FILE AND TRIES TO FIND A PLACE WITHIN THE ┴╥├ WHERE THE FILE
CAN BE SPLIT INTO TWO PIECES. ╔F WHITTLING SUCCEEDS THE FIRST PIECE WILL HAVE
THE ┴╥├ FILE'S ORIGINAL NAME, AND THE SECOND WILL BE NAMED '╨┴╥╘2.┴╥├'.
╘HE FIRST PIECE WILL BE AS BIG AS POSSIBLE, AND STILL BE SMALL ENOUGH TO
├)ONVERT TO AN ╙─┴!. ┬Y REPETITVE ╫)HITTLING, TRULY ╚╒╟┼ ┴╥├ ╞ILES CAN BE
DISSOLVED. ┼VERY TIME YOU WHITTLE, AFTER THE FIRST TIME (ON THAT DISK), YOU
WILL HAVE TO RENAME '╨┴╥╘2.┴╥├' TO A NEW NAME (USE THE '╒SE --─╧╙ COMMANDS' TO
DO THIS). ╫HITTLE WILL FAIL IF AN INDIVIDUAL FILE, WITHIN THE ┴╥├, IS
ENCOUNTERED WHOSE ┴╥├┼─ ╠┼╬╟╘╚ (NOT ORGINAL LENGTH) IS LONGER THAN 193 BLOCKS
(PRETTY RARE!).
╘O MAKE ╫)HITTLE WORK ╔ HAD TO WRITE A ROUTINE WHICH SCANS ┴╥├ FILES WITHOUT
USING ┴╥├. ╧NCE ╔ HAD THIS ROUTINE WORKING ╔ DECIDED TO LET YOU USE IT FOR THE
FOLLOWING NEW OPTION.
┬)ROWSE ┴╥├ FILE. ╘HIS HAS BEEN ADDED IN V4.5. ┘OU SELECT IT FROM THE ═AIN
═ENU BY ╞╔╥╙╘ SELECTING ╫)HITTLE AND THEN HITTING '┬' INTEAD OF RETURN WHEN
ASKED WHETHER YOU WANT TO '╫╚╔╘╘╠┼/┬╥╧╫╙┼ - FILENAME'. ┬ROWSE LETS YOU ╙CAN
THE CONTENT OF AN ┴╥├ FILE ╫╔╘╚╧╒╘ ╒╙╔╬╟ ┴╥├. ╔T GIVES YOU A SIMILAR DISPLAY
AS THE '┴╥├/╠' ┴╥├ COMMAND DOES, EXCEPT THAT;
** IT IS COLORFUL
** THE NUMBERS ARE PROPERLY LINED UP UNDER EACH OTHER
** IT ALSO TELLS YOU THE COMPRESSION FACTOR THAT ┴╥├ WAS ABLE TO ACHIEVE ON
EACH FILE
┴LSO, (╔ SAVED THE BEST FOR LAST) IT SCANS ┴╥├ FILES 2.09 ╘╔═┼╙ ╞┴╙╘┼╥ ╘╚┴╬ ┴╥├
2.50 ─╧┼╙, WITHOUT USING ┴╥├!
╙OME OF THE LESS IMAGINATIVE PEOPLE HAVE ASKED WHAT GOOD IS THE ═)AKE --╙─┴
INTO ┴╥├ OPTION. ╠ET ME GIVE YOU 2 EXAMPLES.
1) ┘OU COULD HAVE CONVERTED AN ┴╥├ INTO AN ╙─┴ AND THEN REALIZED THAT YOU
FORGOT TO INCLUDE A FILE IN THE ╙─┴. ╘O REMEDY THIS SITUATION, YOU COULD MAKE
THE ╙─┴ BACK INTO AN ┴╥├, USE ┴╥├ TO APPEND THE MISSING FILE, AND USE MY
PROGRAM TO CONVERT IT BACK INTO AN ╙─┴. ╔NSTEAD OF HAVING TO GO BACK AND START
FROM SCRATCH.
2) ┼VEN MORE USEFUL, SUPPOSE YOU ONLY HAVE A 64 AND YOU DOWNLOAD THIS TERRIFIC
PROGRAM IN ╙─┴ FORM FOR THE 64, BUT IT REFUSES TO DISSOLVE. ╘HE PROBLEM COULD
BE THAT THE FILE WAS MADE INTO AN ╙─┴ USING THE 128 ╙─┴ MACHINE LANGUAGE (ML)
PREFIX. ╘HIS ╙─┴ WILL NOT DISSOLVE ON A 64 BECAUSE THE 128 ML DOESN'T WORK ON
THE 64. ╫ITHOUT MY PROGRAM, SOMEONE WHO REALLY UNDERSTANDS ╙─┴S AND HOW TO USE
A DISK EDITOR COULD RESCUE THE FILE, BUT ANYONE ELSE WOULD HAVE ONE DIFFICULT
TIME. ╒SING MY PROGRAM, YOU COULD EASILY FIX THE PROBLEM BY '═)AKE(ING)
╙─┴-INTO-┴╥├' AND THEN '├)ONVERT(ING) ┴╥├---TO---╙─┴', IN ALMOST NO TIME! ┘OU
COULD THEN DISSOLVE THE ╙─┴.
V4.4 ADDED THE '┴)NALYSE ---DISK' OPTION. ╒SING SIMPLE CHARACTER GRAPHICS IT
SHOWS YOU THE ┬.┴.═. (┬LOCK ┴LLOCATION ═AP) AND WHERE ALL FILES ON THE DISK
RESIDE. ╔T WILL WORK IN BLACK AND WHITE (BUT WOULD LOSE A LOT!), YOU SHOULD
SEE IT RUN IN COLOR TO REALLY APPRECIATE IT. ┴S IT CHASES DOWN EACH FILE, IT
CHECKS TO SEE THAT THE TRACK AND SECTOR POINTER OF EACH BLOCK ON DISK ARE
VALID, AND ╘╚┴╘ ╘╚┼┘ ─╧ ╬╧╘ ╧╓┼╥╠┴╨ ┴╬╧╘╚┼╥ ╞╔╠┼╙ ┬╠╧├╦ ├╚┴╔╬╙! ╘HIS OPTION
ALONE CAN SAVE YOU HOURS OF TIME WITH A DISK EDITOR ON DAMAGED DISKS. ╔T WILL
NOT WORK ON COMMERCIAL DISKS WITH PHYSICAL DISK ERRORS. ╔T IS INTENDED TO HELP
YOU WITH YOUR NORMAL UNPROTECTED DISKS.
╘HE '╞)OLLOW ---╞ILES ┬LOCK ├HAIN' OPTION HAS BEEN CHANGED SO THAT IT USES THE
'┴)NALYSE ---─ISK'S GRAPHICS ROUTINES BY DEFAULT. ╘HE OLD DISPLAY MODE IS
STILL AVAILABLE AS THE ╠)IST OPTION FOR COMPATIBILITY, AND SO THAT YOU CAN
STILL GET THE LOAD ADDRESSES OF EVERY BLOCK OF A PGM FILE ON THE SCREEN OR
PRINTER.
╙OME USERS HAVE NOT YET FIGURED OUT THAT IF YOU AQUIRE AN ┴╥├ FILE YOU CAN
DE-┴╥├ IT BY USING THIS PROGRAM TO CONVERT IT TO AN ╙─┴ AND THEN DISSOLVE IT.
╘HIS IS USUALLY MUCH FASTER (AND MUCH EASIER ON YOUR DRIVE, ESPECIALLY FOR
SINGLE DRIVE PEOPLE) THAN USING ┴╥├ TO DE-┴╥├ THE ┴╥├ FILE.
╧NCE ┴╟┴╔╬, ═ORE ┬╒╟╙ WERE MERCILESSLY ├╥╒╬├╚┼─. :>
===============================================================================
3.7 TO 4.0 ╓ERSION ╬OTES
===============================================================================
╫HEN YOU ├)ONVERT AN ┴╥├ TO AN ╙─┴, ╓ERSION 4.0 NOW CORRECTS THE FILE LENGTH OF
THE ╙─┴ AND ─┼╠┼╘┼╙ THE ┴╥├ FILE. ┘OU CAN GET BACK THE ORIGINAL .┴╥├ FILE WITH
THE NEW OPTION:
═)AKE ----- ╙─┴ INTO ┴╥├
┴FTER YOU HAVE ═)ADE AN ╙─┴ INTO AN ┴╥├, ╓ALIDATING THE DISK IS ┴ ╟╧╧─ ╔─┼┴!
╔T WON'T HURT IF YOU DON'T VALIDATE, BUT YOU WILL LOSE THE USE OF A FEW
(8+) BLOCKS ON THAT DISK. ╘HOSE BLOCKS ARE STILL MARKED AS IN USE IN THE ┬┴═
(┬LOCK ┴LLOCATION ═AP).
╘HE ┬ROWSE ─ISK OPTION HAS BEEN ADDED.
╧NCE AGAIN, ═ANY ┬╒╟╙ WERE ╙╤╒┴╙╚┼─. :>
===============================================================================
╥ESTRICTIONS ╞OR ├ONVERTING AN ┴╥├ TO AN ╙─┴
===============================================================================
--╘HE ┴╥├ FILE CANNOT BE LARGER THAN 193 BLOCKS (USE ╫)HITTLE FIRST).
--╘HE ├64 (OR THE 128 IN 64 MODE) AND THE 1541 (OR QUITE COMPATIBLE) ARE THE
╧╬╠┘ DEVICES WHICH WORK AT THIS TIME.
--╘HE FILENAME TO BE CONVERTED (TO AN ╙─┴) MUST END IN '.┴╥├'.
--┴ND OF COURSE THE .┴╥├ FILE MUST BE IN ┴╥├ FORMAT.
===============================================================================
╒SING THE ╨ROGRAM
===============================================================================
╠OAD '┴╥├-╙─┴ V4.6',8,1. ╘HERE WILL BE A SHORT DELAY.
╚IT RETURN ON THE ├REDITS SCREEN AND YOU WILL BE AT THE MAIN MENU (WHICH HAS
THE ┴╥├ ╘╧ ╙─┴ ╓4.6 GRAPHIC AT THE TOP). ╘HE OPTIONS FROM THE MAIN MENU ARE:
(╠)OAD ─IRECTORY
╘HIS OPTION WILL LOAD THE DIRECTORY OF THE DISK IN DRIVE 8 INTO A TABLE IN
CORE. ┴S IN MOST OF THE OTHER OPTIONS, YOU ARE GIVEN A CHANCE TO ┴┬╧╥╘ BY
HITTING THE '┴' KEY, OR TO CONTINUE BY HITTING RETURN.
(─)ISPLAY ─IR (IN CORE)
╘HIS OPTION WILL DISPLAY THE CONTENTS OF THE DIRECTORY TABLE ONTO YOUR
SCREEN. ╬OTE: THE ╙╚╔╞╘ KEY WILL HALT THE PRINTING ON THE SCREEN UNTIL IT IS
RELEASED. ╘HE LOAD DIRECTORY ROUTINE WILL BE CALLED IF NO DIRECTORY IS IN THE
DIRECTORY TABLE.
(┬)ROWSE ─ISK
╘HIS OPTION WILL ALLOW YOU TO ╙CAN DISKS, WHILE REMAINING IN THE PROGRAM.
(╨)ICK A ╞ILE
╘HIS IS A NIFTY ROUTINE WHICH ALLOWS YOU TO SELECT THE FILE YOU WANT TO USE
FROM THE DIRECTORY TABLE. ╔F NECCESSARY, THE LOAD DIRECTORY ROUTINE WILL BE
CALLED. ╒SE THE CURSOR KEYS TO MOVE THE SELECT CURSOR. ╒SE '+' OR '-' TO PAGE
FORWARD OR BACKWARD. ╒SE '╥┼╘╒╥╬' TO SELECT THE HIGHLIGHTED FILE. ╒SE '╚' TO
VIEW THE ╚ELP ╙CREEN. ═ULTIPLE PAGES ARE SUPPORTED (144 FILES ═┴╪╔═╒═).
(╞)OLLOW ╞ILE'S ┬LOCK ├HAIN
╘HIS OPTION FOLLOWS THE BLOCK POINTERS OF THE ╨╔├╦ED FILE AND PRINTS THEM ON
THE SCREEN. ╔T NOW USES THE ╟RAHPICS DISK ROUTINES FROM THE ┴)NALYSE DISK
OPTION. ╔F YOU WANT THE LOAD ADDRESS, IN DECIMAL AND HEX, OF EACH TRACK AND
SECTOR OF THE FILE THEN CHOSE '╠' (OR '╨' FOR THE PRINTER, DEVICE 4 ONLY). ╔T
TELLS YOU ON WHAT SECTORS OF YOUR DISK A PARTICULAR FILE RESIDES. ╔N THE
DEFAULT GRAPHICS MODE, THE POINTER CHECKS (FOR NEXT TRACK AND SECTOR) ARE MORE
STRINGENT! ╘HE ╨ICK ╞ILE (AND THERFORE THE ╠OAD ─IRECTORY) ROUTINES WILL BE
CALLED, IF NECCESSARY.
(╓)ERFIY ╞ILES ╠ENGTH.
╘HIS OPTION USES THE GRAPHICS DISPLAY OF ┴)NALYSE DISK AND WILL FOLLOW THE
SELECTED DISK FILE UNTIL IT'S END. ╔T THEN COMPARES THE LENGTH IT DERIVED WITH
THE LENGTH IN THE DIRECTORY. ╔F THEY ARE DIFFERENT, IT GIVES YOU THE CHANCE TO
CORRECT THE THE LENGTH STORED IN THE DIRECTORY. ╬OTE: ├OMMODORES VALIDATE
ROUTINE ─╧┼╙ ╬╧╘ SEEM TO ALTER THE LENGTH IN THE DIRECTORY! ╘HE ╨ICK ╞ILE (AND
THERFORE THE ╠OAD ─IRECTORY) ROUTINES WILL BE CALLED, IF NECCESSARY.
(├)ONVERT ┴╥├---TO---╙─┴
╘HIS OPTION IS THE ONE THAT MAKES THIS PROGRAM SO POPULAR. ╔T CHECKS THE
╨╔├╦┼─ FILE TO MAKE SURE THAT IT ENDS IN .┴╥├ AND THAT IT IS LESS THAN 194
BLOCKS LONG. ╘HE ╨ICK ╞ILE (AND THERFORE THE ╠OAD ─IRECTORY) ROUTINES WILL BE
CALLED,IF NECCESSARY. ╔F EVERYTHING IS OK, YOU ARE GIVEN ONE LAST CHANCE TO
┴┬╧╥╘ BEFORE THE CONVERSION TAKES PLACE. ╘HEN YOU ARE ASKED FOR THE NAME OF
THE ╙─┴ FILE (WHICH NICELY DEFAULTS TO THE SAME NAME AS THE ORIGINAL FILE WITH
THE .┴╥├ REPLACED WITH .╙─┴).
(═)AKE ╙─┴-INTO-┴╥├
╘HIS OPTION IS UNIQUE TO THIS PROGRAM. ╔T WILL STRIP THE ╙─┴ PREFIX (AND
THE TITLE SCREEN) FROM AN ╙─┴ AND GIVE YOU BACK A .┴╥├ FILE! ╘HIS SHOULD WORK
(HOPEFULLY) EVEN IF THE ╙─┴ WAS NOT CREATED WITH THIS PROGRAM (OR ON A 64, COULD HAVE BEEN A 128)! ╘HE PROGRAM IS FAIRLY PICKY, AND TRIES TO MAKE SURE
THAT THE ╙─┴ IS REALLY AN ╙─┴ BEFORE CONTINUING. ╔F NO FILE HAS BEEN SELECTED
THE ╨ICK A ╞ILE ROUTINE IS CALLED. ╔F EVERYTHING IS OK, YOU ARE GIVEN ONE LAST
CHANCE TO ┴┬╧╥╘ BEFORE THE CONVERSION TAKES PLACE. ╘HEN YOU ARE ASKED FOR THE
NAME OF THE ┴╥├ FILE THAT YOU WANT TO CREATE. ╙EE V3.7-V4.0 NOTES ON UNFREED
BLOCKS!
(╫)HITTLE ┴RC--TO--╙─┴ (╙EE ╓4.6 VERSION NOTES!)
╘HIS IS A NEW OPTION WHICH REALLY HAS TWO PARTS. ╫)HITTLE AND ┬)ROWSE.
┬OTH OPTIONS LET YOU VIEW THE CONTENTS OF AN ┴╥├ FILE. ╔F IT IS AN ╙─┴ THEN
YOU CAN ═)AKE IT INTO AN ┴╥├, AND THEN VIEW IT'S CONTENTS, BUT IF YOU DO SO,
YOU WILL LOSE THE ORIGINAL TITLE SCREEN. ┬OTH RUN THROUGH THE ┴╥├ FILE AT
2.09 ╘╔═┼╙ ╘╚┼ ╙╨┼┼─ ╧╞ ┴╥├S (V2.50) '┴╥├/╠' COMMAND! ╙ORRY ├HRIS ╙MEETS.
╔F NO FILE HAS BEEN SELECTED THE ╨ICK A ╞ILE ROUTINE IS CALLED.
┬)ROWSE DOES EXACTLY WHAT IT SOUNDS LIKE, IT LETS YOU EXAMINE THE CONTENT OF
AN ┴╥├ WITHOUT ALTERING IT. ╘O SELECT BROWSE JUST HIT '┬' WHEN YOU SEE THE
'╫╚╔╘╘╠┼/┬╥╧╫╙┼ - FILE' PROMPT.
╫)HITTLE IS A SPECIAL PURPOSE FUNCTION FOR SINGLE DRIVE PEOPLE, OR THOSE WHO
NEED TO DE-┴╥├ A ╚╒╟┼ ┴╥├ FILE AND ARE INTIMIDATED BY (OR UNAWARE OF) USING ┴╥├
WITH TWO DRIVES. ╫)HITTLE ATTEMPTS TO WHITTLE OFF THE LARGEST POSSIBLE ╙─┴ABLE
SIZE PIECE FROM THE BEGINING OF AN ┴╥├ FILE. ╔T SCANS THE ┴╥├ FILE AND STOPS
WHEN IT DETERMINES WHETHER A WHITTLE IS POSSIBLE. ┴ WHITTLE IS IMPOSSIBLE IF A
FILE, WITHIN THE ┴╥├, EXCEEDS, IN ┴╥├ ╞╔╠┼ ╠┼╬╟╘╚, 193 BLOCKS (FAIRLY ╥┴╥┼!).
╔F A WHITTLE IS POSSIBLE, YOU ARE TOLD SO. ╔F WHITTLE IS NOT YOU ARE GIVEN A
MESSAGE TO THAT EFFECT, AND WHITTLING IS ABORTED. ╔F IT IS POSSIBLE, THEN YOU
ARE GIVEN ONE LAST CHANCE TO ABORT (AS USUAL) AND THEN WHITTLING COMMENCES. ╔T
IS PRETTY FAST. ┘OU WILL WIND UP WITH TWO FILES ON THE DISK. ╘HE FIRST ONE
WILL HAVE THE NAME OF THE ORIGINAL ┴╥├ FILE. ╘HAT IS THE ONE THAT IS SMALL
ENOUGH TO BE CONVERTED TO AN ╙─┴. ╘HE SECOND IS A FILE CALLED '╨┴╥╘2.┴╥├'. ╔T
IS THE REMAINING PROTION OF THE ┴╥├, WHICH MAY OR MAY NOT REQUIRE ANOTHER
WHITTLE TO BRING IT DOWN TO AN ╙─┴ABLE SIZE. ╔F YOU HAVE TO DO ANOTHER WHITTLE
ON '╨┴╥╘2.┴╥├', YOU WILL HAVE TO RENAME '╨┴╥╘2.┴╥├' TO SOME OTHER NAME (ENDING
IN '.┴╥├'), BECAUSE THIS PROGRAM CHECKS TO MAKE SURE THAT '╨┴╥╘2.┴╥├' DOES NOT
EXIST BEFORE WHITTLING COMMENCES. ╔F NO FILE HAS BEEN SELECTED THE ╨ICK A ╞ILE
ROUTINE IS CALLED.
(╙)RATCH ╞ILE XXXXXXXXXXXXXX
╘HIS OPTION ALLOWS YOU TO DELETE FILES FROM THE DISK. ╘O KEEP THE TABLE
IN SYNC WITH THE DISK, THE DIRECTORY IS RELOADED, IF A FILE IS INDEED
SCRATCHED.
┘OU ARE GIVEN A CHANCE TO ┴┬╧╥╘ AND THE SCREEN CHANGES TO ╥┼─ TO REMIND YOU
THAT IT IS A DANGEROUS OPTION. ╘HE ╨ICK ╞ILE (AND THERFORE THE ╠OAD ─IRECTORY)
ROUTINES WILL BE CALLED, IF NECCESSARY.
(┴)NALYZE ─ISK
╘HIS OPTION WAS ADDED TO ALLOW YOU TO INVESTIGATE YOUR UNPROTECTED DISKS.
╔T USES SIMPLE CHARACTER GRAPHICS (IN COLOR) TO SHOW YOU WHERE EVERY FILE ON
YOUR DISK RESIDES. ╔T CHECKS THE FILE POINTERS TO MAKE SURE THAT EACH BLOCK IS
ALLOCATED IN THE ┬.┴.═., THAT THEY ARE LEGAL (NOT GREATER THAN 35, USE THE
DIRECTORY TRACK 18) AND THAT THEY ─╧ ╬╧╘ ╧╓┼╥╠┴╨ ╘╚┼╔╥ ╧╫╬ (╧╥ ╧╘╚┼╥) ╞╔╠┼
├╚┴╔╬╙, OR ╨╧╔╬╘ ╘╧ ╘╚┼═╙┼╠╓┼╙!
╒NFORTUNATELY, BECAUSE IT RELYS SO HEAVILY ON COLOR, A PRINTER OPTION IS NOT
SUPPORTED. ╔F YOU HAVE TO HAVE A HARD COPY THEN EITHER: USE A ╨OLAROID, RUN
IT ON A MACHINE WITH ╙UPER ╙NAPSHOT, OR RESORT TO PENCIL AND PAPER. ╞OR
ADVANCED USERS, THIS OPTION MAY HELP YOU ╞╔╪ THAT DISK YOU PUT ASIDE WAITING
FOR THE RIGHT UTILITY TO COME ALONG. ╔ JUST LIKE TO WATCH IT RUN AND SEE WHERE
├┬═ ─╧╙ DECIDED TO PUT EVERYTHING.
(╒)SE ─╧╙ ├OMMAND
╘HIS OPTION ALLOWS YOU TO SEND ─╧╙ COMMANDS TO THE DISK DRIVE. ╙EE YOUR
1541 DISK MANUAL IF YOU ARE NOT FAMILIAR WITH THE COMMANDS. ┴FTER YOU HAVE
ISSUED 1 OR MORE DISK COMMANDS, AND HIT RETURN TO EXIT THE DOS COMMAND SECTION
YOU ARE ASKED TO RELOAD THE DIRECTORY. ┘OU SHOULD RELOAD THE DIRECTORY, IF YOU
CHANGED THE CONTENTS OF THE DIRECTORY BY ANY OF THE COMMANDS YOU ISSUED.
