.... . THIS COMMAND IS USED TO EXTRACT F
ILES FROM AN ARCHIVE. IF NO PATTERNS ARE
. SPECIFIED, THEN ARC WILL EXTRACT ALL
FILES FROM THE ARCHIVE. SOME EXAMPLES:.
. ARC/X A:SQ. - EXTRACTS ALL FILES FROM
SQ.ARC ON DRIVE 8,0 AND PUTS THEM ON THE
DEFAULT . DIRECTORY.. . ARC/X A:SQ *.
- SAME AS THE ABOVE. . ARC/X/F B:TEMP.A
RC . - EXTRACTS ALL FILES FROM TEM
P.ARC ON DRIVE 8,1 AND PUTS THEM ON THE
DISKETTE. IN DRIVE F: (10,1). . ARC/X/
GRALPH F:SECRET . - EXTRACTS THE FILES I
N AN ARCHIVE WHICH HAS BEEN ENCRYPTED WI
TH THE PASSWORD. RALPH, AND PLACES THE
M ON THE DEFAULT DIRECTORY.. . ARC/E C:B
OOK030386 CHAPTER1 . - EXTRACTS ONLY T

/X AND ARC/E ARE SYNONYMS. . . .
DISPLAY ARCHIVE CONTENTS....... . . ARC
/L <[D:]ARCHNAME[.ARC]>. . THIS IS USED
TO GET A LISTING OF THE FILES IN AN ARCH
IVE. THE LISTING WILL . DISPLAY THE FILE
NAME, FILETYPE, UNSQUEEZED AND SQUEEZED
LENGTHS (IN DISK . BLOCKS), AND THE COMP
RESSION METHOD USED. SOME EXAMPLE: . . A
RC/L B:SQ. - GIVES A LISTING OF THE FILE

HIS IS USED TO VERIFY THE CONTENTS OF AN
ARCHIVE. ARC CALCULATES A TWO BYTE . CH
ECKSUM FOR EACH FILE IN AN ARCHIVE. WHEN
YOU VERIFY AN ARCHIVE, ARC . CALCULATES
A NEW CHECKSUM AND COMPARES IT WITH THE
CHECKSUM STORED WHEN THE . FILE WAS ARC
HIVED. IF THEY DO NOT MATCH, AN ERROR ME
SSAGE IS DISPLAYED . INDICATING THAT THE
ARCHIVE MAY NOT UN-COMPRESS PROPERLY. N
OTE: IF YOU HAVE . USED A PASSWORD WHEN
CREATING THE ARCHIVE YOU NEED NOT SPECIF
Y IT SINCE THE . ENCRYPTED BYTES ARE USE
D IN CALCULATING THE CHECKSUM. EXAMPLE:.
. ARC/V B:USQ.ARC - VERIF
IES USQ.ARC ON UNIT 8,1. ARC/V B:USQ USQ
.LB - VERIFIES ONLY THE FILE
'USQ.LB' IN THE ARCHIVE.

A BIT OF THEORY.....................
. RUN-LENGTH ENCODING............ A
LL METHODS OF DATA COMPRESSION TAKE . AD
VANTAGE OF REDUNDANCY OF ONE FORM OR ANO
THER. RUN-LENGTH CODING IS ONE OF . THE
SIMPLEST, AND OFTEN THE MOST EFFECTIVE
TECHNIQUES. GRAPHICS FILES MAY . OFTEN
CONTAIN LONG SEQUENCES OF THE SAME BYTE.
ZEROS FOR BLANK SPACE, OR 255'S. FOR FI
LLED IN SPACE. RUN-LENGTH CODING RECODES
THESE LONG SEQUENCES AS . SHORTER CON
TROL SEQUENCES. FOR EXAMPLE, A GRAPHICAL
IMAGE STORED IN RAM MAY. LOOK SOMETHI
NG LIKE THE FOLLOWING IF VIEWED WITH THE
MACHINE LANGUAGE MONITOR:. . . .:2
000 00 00 00 00 00 00 00 00. .:2008
00 00 FF FF FF FF FF 00. .:2010 00
00 00 00 00 00 00 00. .:2018 A0 0B
FF FF FF FF FF FF. AND SO ON..... .
THIS COULD BE STORED ON DISK AS THE SEQU
ENCE:. . 00 00 0A 00 FF 05 00 00 09 A0
0B 00 FF 06 . . THE FIRST ZERO IS A CO
NTROL CHARACTER. WHEN THE UNSQUEEZE ROUT
INE ENCOUNTERS. A ZERO IT GETS THE NEXT
TWO CHARACTERS AND INTERPRETS THEM AS A
CHARACTER . IDENTIFIER AND A COUNT. THU
S THE FIRST 3 BYTE SEQUENCE IS INTERPRET
ED AS 10 . ZEROS, THE NEXT 3 BYTE SEQUEN
CE AS 5 FF'S AND SO ON. WHEN A CHARACT
ER IS NOT. REPEATED, IT IS SIMPLY CODED
DIRECTLY TO THE OUTPUT FILE. (THE $A0 AT
$2018 . ABOVE) AND SO THE ABOVE IS SQU
EEZED FROM 32 BYTES DOWN TO 14. . . TH
ERE IS ONE SLIGHT PROBLEM WITH THIS METH
OD. SUPPOSE YOU ARE USING A ZERO-. BYTE
AS THE CONTROL CHARACTER. IF A SEQUENCE
OF ONLY ONE ZERO IS ENCOUNTERD, . YOU C
ANNOT CODE IT TO THE OUTPUT FILE SINCE I
T WILL BE INTERPRETED AS A . CONTROL CHA
RACTER. YOU MUST SEND A THREE BYTE CONTR
OL SEQUENCE TO CODE THE . SINGLE ZERO. A
RC ATTEMPTS TO CIRCUMVENT THIS PROBLEM B
Y CHOOSING THE BYTE THAT. OCCURS LEAST O
FTEN IN THE FILE AS THE CONTROL CHARACTE
R. AN EXAMPLE OF THIS . WOULD BE AS FOLL
OWS:. . . .:0801 06 08 01 00 8F 00
0C 08. .:0809 02 00 8F 00 12 08 03
00. .:0811 8F 00 00 00 00 00 00 00
. AND SO ON..... . THIS WOULD BE ST
ORED ON DISK AS THE SEQUENCE:. . 06 0
8 01 00 00 01 8F 00 00 01 0C 08 02 00 00
01 . 8F 00 00 01 12 08 03 00 00 01 8
F 00 00 07 ..... . . WE WENT FROM 24 B
YTES TO 30! NOT MUCH OF A SAVINGS. . . .
. HUFFMAN CODING................
.. . HUFFMAN CODING IS SOMEWHAT MORE COM
PLEX. IT TAKES ADVANTAGE OF THE FACT THA
T . SOME CHARACTERS ARE USED MORE OFTEN
THAN OTHERS IN MOST FILES. TEXT FILES .
CONTAIN MANY SPACES, AND VOWELS ARE M
UCH MORE ABUNDANT THAN CONSONANTS. THE.
HUFFMAN ALGORITHM .CONVERTS FIXED LENGT
H CODES (8 BIT CHARACTERS) INTO CODES .
WHOSE LENGTH IN BITS IS INVERSELY PROPOR
TIONAL TO THEIR PROBABILITY OF . OCCURA
NCE IN THE DATA FILE. FOR EXAMPLE, SUP
POSE YOUR DATA FILE LOOKED . SOMETHING
LIKE THIS:. . ABRACADABRA. . THE CHARA
CTER FREQUENCY DISTRIBUTION IS AS FOLLOW
S:.
TOTAL BITS TOTAL BITS. CHARACTE
R FREQUENCY HUFFMAN CODE. UNSQUEEZED
SQUEEZED . --------- --------- --
----------. ---------- ----------.
A 5 0 8
* 5 = 40 1 * 5 = 5. B
2 10 8 * 2 = 16 2 *
2 = 4. R 2 11
1 8 * 2 = 16 3 * 2 = 6.
C 1 1100 8 * 1

. WE COULD REPRE
SENT THIS INFORMATION AS A BINARY TREE:
. . .
. C
. /
. A B /---- D
. / / /
. ROOT --- --- --- R
. . . . TO GET THE HUFFMAN CODE WE C
ODE A 0 BIT EACH TIME WE TRAVERSE A BRAN
CH TO THE. LEFT, AND A 1 BIT EACH TIME W
E TRAVERSE THE TREE TO THE RIGHT. THUS T
HE CODES . ARE GENERATED AS IN THE TABLE
ABOVE.. . THE MOST FREQUENTLY OCCURING
CHARACTERS ARE KEPT CLOSEST TO THE ROOT
AND THUS . HAVE SHORTER CODES. THOSE WIT
H LOWER FREQUENCIES OF OCCURANCE ARE KEP
T FURTHER. AWAY AND GET LONGER CODES. TH
E RESULT IS OFTEN A FILE THAT IS SIGNIF
ICANTLY . SHORTER THAN THE ORIGINAL. .
. WHEN ALL BYTES OCCUR WITH ABOUT THE S
AME FREQUENCY, AS IN PRG FILES, THEN .
ALL THE CODES ARE ABOUT THE SAME LENGTH
AND NOT MUCH IS GAINED. IN FACT, . S
INCE THE DE-CODING INFORMATION MUST B
E INCLUDED IN THE OUTPUT FILE, THE. R
ESULT CAN OFTEN BE LONGER, PARTICULARLY
ON SHORT FILES.. . . . "ANALYZ
E" EXTERNAL FUNCTION.... . . FOR THOSE O
F YOU THAT ARE INTERESTED IN STATISTICS,
WE HAVE INCLUDED A SMALL . UTILITY PROG
RAM WITH ARC THAT ANALYZES THE FREQUENCY
DISTRIBUTION OF THE BYTES. IN A FILE AN
D GRAPHICALLY DISPLAYS THE RESULTS. ON T
HE TOP PORTION OF THE . SCREEN YOU WILL
SEE THE FREQUENCY DISTRIBUTION OF THE BY
TES IN THE FILE. ON . THE BOTTOM PORTION
IS A BAR GRAPH REPRESENTING THE LENGTHS
OF THE HUFFMAN . CODES GENERATED BY THE
SQUEEZE ALGORITHM. A HUFFMAN CODE CAN B
E ANYWHERE FROM. 0 TO 24 BITS IN LENGTH.
EACH BIT IN THE HUFFMAN CODE IS REPRESE
NTED BY TWO . PIXELS ON THE GRAPHICS SCR
EEN. TO RUN THE UTILITY YOU MUST HAVE AR
C IN MEMORY. AND TYPE: . . A:ANALYZE [D:
]FILENAME. . THE PROGRAM WILL THEN READ
THROUGH 'D:FILENAME' AND DISPLAY A FREQU
ENCY . DISTRIBUTION FOR THE FILE.. . . .
ARC VERSIONS...................
. . WE WILL MAKE EVERY EFFORT TO KEEP A
RC FILES UPWARD COMPATIBLE. THUS, AN . A
RCHIVE CREATED WITH VERSION 1.00 CAN BE
DE-ARCHIVED BY ANY VERSION OF ARC . NUM
BERED 1.00 OR HIGHER. THE REVERSE, HOWEV
ER, WILL NOT BE POSSIBLE SINCE . NEW PA
CKING METHODS WILL BE INTRODUCED IN FUTU
RE VERSIONS OF ARC. . . WE HOPE YOU ENJO
Y USING ARC, AND LOOK FORWARD TO HEARING
YOUR COMMENTS AND . SUGGESTIONS. . .

ANGES IN ARC VERSION 1.30. . 1) - THERE
WAS A BUG IN VERSION 1.00 WHICH OCASIONA
LLY MADE A FILE ONE BLOCK . LONGER
THAN IT SHOULD BE. THIS ONLY OCCURED WHE
N THE SQUEEZED FILE WAS AN. EXACT M
ULTIPLE OF 2032 BITS. THIS BUG HAS BEEN
CORRECTED. . 2) - THE /G OPTION HAS BEEN
ADDED TO ALLOW FILES TO BE ENCRYPTED. Y
OU SUPPLY A. PASSWORD OF UP TO 9 CH
ARACTERS, AND THIS PASSWORD IS USED TO E
NCRYPT THE . FILE. WHEN DE-ARCHIVIN
G THE FILE, THE CORRECT PASSWORD MUST BE
SUPPLIED. . ENCRYPTED FILES WILL V
ERIFY OK, AND WILL DE-ARCHIVE WITHOUT PR
OBLEM IF NO. PASSWORD IS SUPPLIED.
THEY WILL HOWEVER, STILL BE ENCRYPTED AF
TER DE-. ARCHIVING WITHOUT A PASSWO
RD. . 3) - DRIVES G AND H ARE NOW USED
. (UNIT 11 DRIVES 0 AND 1). 4) - RUN-LEN
GTH COMPRESSION HAS BEEN ADDED, AND SHOW
S UP AS 'PACKED' FILES ON. AN ARCHI
VE DIRECTORY. . . 06 APR 86 - CHRIS
SMEETS. . . . CHANGES IN ARC VERSION 1.
31. . 1) - ADDED THE RENAME ( REN ) COMM
AND.. 2) - DRIVES G AND H WERE ADDED IN
VERSION 1.30, BUT DID NOT WORK PROPERLY.
. THIS HAS BEEN CORRECTED.. 3) - A
'/W' SWITCH HAS BEEN ADDED TO THE DIR C
OMMAND TO ALLOW A MORE COMPACT . DI
RECTORY DISPLAY. ALSO MORE THAN ONE DIRE
CTORY PATTERN MAY NOW BE . SPECIFIE
D ON THE COMMAND LINE. . . 20 MAY 8
6 - CHRIS SMEETS . . . . CHANGES IN ARC
VERSION 1.34. . 1) - ADDED THE /Q SWITCH
TO GET.. 2) - ALLOWED FOR SELECTIVE EXT
RACTION OF FILES FROM AN ARCHIVE.. 3) -
ADDED THE 'ANALYZE' EXTERNAL FUNCTION..
4) - FIXED A BUG IN ARC/C/GABC. ARC'S NU
MBERED 1.31 OR LESS ONLY RECOGNIZED .
THE FIRST CHARACTER OF THE PASSWORD.
THIS HAS BEEN CORRECTED.. 5) - SPEAKING
OF BUGS..... ARC WILL OCCASIONALLY
REPORT A CHECKSUM ERROR WHEN UN-ARCHING
OR . VERIFYING A 'PACKED' FILE. THI
S IS DUE TO AN ERROR IN THE CHECKSUM .
CALCULATION AND DOES NOT REFLECT A P
ROBLEM WITH THE FILE. YOU CAN VERIFY.
THIS FOR YOURSELF BY RENAMING THE PRO
BLEM FILE AND RE-ARCHIVING IT. . IF
THE NAME IS SHORTER OR LONGER, THE ARCH
IVE NO LONGER ENDS ON A DISK . BLOC
K BOUNDARY AND THE CHECKSUM IS OK! UNFOR
TUNATELY WE'VE BEEN HAVING . SOME T
ROUBLE LOCATING THIS BUG SO IT'S STILL T
