            ╨ERMISSION IS HEREBY GRANTED TO REPRODUCE THIS PROGRAM
            AND DOCUMENTATION FILE FOR PERSONAL USE ONLY.  ╘HIS

            ╔ ENCOURAGE COPYING AND DISTRIBUTION, SUBJECT TO

├╥╧╙╙ ╠╔╬╦ IS A SHORT ┬┴╙╔├ 7 PROGRAM FOR USE ON THE ├-128 WITH A
1571 DRIVE.  ╔T ALLOWS YOU TO READ A FILE INTO A 45 K ╥┴═ BUFFER FROM ANY ONE
OF THE FOLLOWING SEVEN DISK FORMATS:

    ╙┼╤ - ┴╙├╔╔
    ╙┼╤ - WITH ╨┼╘╙├╔╔ <> ┴╙├╔╔ CONVERSION
    ╨╥╟ - ┴╙├╔╔
    ╨╥╟ - WITH SCREEN CODE <> ┴╙├╔╔ CONVERSION
    ├-128 ├╨/═ SINGLE SIDED
    ├-128 ├╨/═ DOUBLE SIDED
    ╔┬═ ╨├-─╧╙ DOUBLE SIDED, 9 SECTORS/TRACK

╘HE BUFFER CAN THEN BE WRITTEN TO ANOTHER DISK IN ANY OF THE SAME LIST OF
FORMATS OR TO A PRINTER.  (╔T SHOULD BE NOTED THAT THE ╔┬═ ╨├-─╧╙ DOUBLE
SIDED FORMAT IS ╬╧╘ THE SAME AS THE "╔┬═-─╙" WHICH IS SUPPORTED BY ├-128 ├╨/═
MODE.  ╘HE LATTER FORMAT IS USED BY ├╨/═-86 WHICH IS THE 16 BIT VERSION OF
├╨/═ DESIGNED TO RUN ON THE ╔┬═-╨├ INSTEAD OF ╨├-─╧╙.  ╨├-─╧╙ AND ├╨/═-86
ARE NOT COMPATIBLE.)  ├╥╧╙╙ ╠╔╬╦ IS SIMPLE TO USE, JUST FOLLOW THE PROMPTS ON
THE SCREEN.  ╧NE WORD OF CAUTION, HOWEVER.  ┬ECAUSE THE 1571 IS NOT A TRUE
╨├-─╧╙ DISK DRIVE, NEVER WRITE ╨├-─╧╙ FILES TO AN ORIGINAL, IRREPLACEABLE
DISK.  ╨LAY IT SAFE, ALWAYS USE SCRATCH DISKS FOR WRITING FILES.  (┴LTHOUGH
╔ HAVE HAD NO PROBLEMS WITH DISKS FROM THREE DIFFERENT ╔┬═-╨├S AND TWO ╨├
COMPATIBLES, THE POSSIBILITY DOES EXIST FOR MIS-MATCHED SECTOR TIMING, ETC.
╘HIS COULD HOPELESSLY CORRUPT THE DISK BEING WRITTEN TO.)

├╥╧╙╙ ╠╔╬╦ USES BURST MODE ON THE 1571 TO READ AND WRITE ╨├-─╧╙ AND ├╨/═
FILES, CONSEQUENTLY IT IS QUITE FAST.  (┴ DETAILED DESCRIPTION OF 1571
BURST MODE AND HOW TO USE IT IS PRESENTED IN A SERIES OF ARTICLES BY
THIS AUTHOR IN ╘╨╒╟ MAGAZINE, STARTING IN ═AY 1986.)  ┴ TYPICAL CONVERSION
OF A 16K (65 ╙┼╤ BLOCK) TEXT FILE FROM ╙┼╤ ╨┼╘╙├╔╔ TO ╨├-─╧╙ TAKES ABOUT
65 SECONDS, INCLUDING ABOUT 25 SECONDS OF "OVERHEAD" REQUIRED TO
DECODE AND RECODE THE ╨├-─╧╙ DIRECTORY AND FILE ALLOCATION TABLE (╞┴╘).
╬OTICE THAT ╔ SPECIFY THE CONVERSION OF A TEXT FILE.  ╘HIS BRINGS UP A
GENERAL CAVEAT: PROGRAM FILES WRITTEN TO RUN UNDER ╨├-─╧╙ (I.E. WITH A FILE
TYPE OF .┼╪┼ OR .├╧═) WILL NOT WORK IN ├-128 MODE OR ├╨/═ MODE (THE ├╨/═
EXECUTABLE FILE ALSO HAS A FILE TYPE OF .├╧═, BUT THE TWO ARE NOT
INTERCHANGEABLE) OR VICE VERSA.  ╚OWEVER, IF YOU DOWNLOAD A ├╨/═ PROGRAM TO
A ╨├-─╧╙ DISK AND THEN CONVERT THE FILE TO ├╨/═ FORMAT, THE PROGRAM WILL
WORK IN ├╨/═ MODE ON THE ├-128.  ╘HIS IS USEFUL, FOR EXAMPLE, IF YOU DO NOT
HAVE A MODEM ON YOUR ├-128 BUT HAVE ACCESS TO ONE ON AN ╔┬═-╨├ WHERE YOU
WORK.  ╘HE SAME GOES FOR DOWNLOADING TO A ├-128 PROGRAM TO ╨├-─╧╙ THEN
CONVERTING TO A ╨╥╟ ┴╙├╔╔ FILE OR DOWNLOADING TO ╙┼╤ FORMAT IN ├-128
MODE AND THEN CONVERTING TO ├╨/═ FORMAT.  (╘HE ORIGINAL ├╨/═ SYSTEM FILES
FOR THE ├-128 DID NOT SUPPORT A MODEM.  ╘HE UPGRADED VERSION NOW DOES.)
╘EXT AND DATA FILES, ON THE OTHER HAND, FROM ONE MACHINE CAN USUALLY BE
USED WITHOUT TROUBLE ON THE OTHER.  ╘EXT FILES TRANSFERRED USING SCREEN
CODE ╨╥╟ FILES MAY REQUIRE REFORMATTING ON THE TARGET WORD PROCESSOR.
╙CREEN CODE FILES WRITTEN BY ├╥╧╙╙ ╠╔╬╦ MAY NOT WORK WITH ALL ├-128
WORD PROCESSORS.  ╙OME WP'S, SUCH AS ╨APERBACK ╫RITER 128, INCLUDE A
HEADER BLOCK AT THE BEGINNING OF THE FILE.  ╘HE HEADER CONTAINS INFO
ON THE FILE CHARACTERISTICS SUCH AS MARGINS ETC.  ╔F IT IS NOT PRESENT,
THE WP MAY NOT BE ABLE TO READ THE FILE CORRECTLY.  ╘HESE WP'S CAN
USUALLY READ ╙┼╤ FILES AS WELL, HOWEVER, SO IT IS BETTER TO WRITE
A ╙┼╤ FILE WITH ├╥╧╙╙ ╠╔╬╦ FOR USE ON MOST WP'S.  ├╥╧╙╙ ╠╔╬╦ CAN
READ ╨╥╟ TEXT FILES WITH HEADERS, BUT YOU MUST DELETE THE HEADER BLOCK
WITH THE TARGET WP.   ┬┴╙╔├ PROGRAM LISTINGS CREATED ON ONE MACHINE
CAN OFTEN BE USED ON ANOTHER WITH ONLY MINOR EDITING.  ├-128 ┬┴╙╔├ 7.0,
├╨/═ ═┬┴╙╔├ AND ╔┬═-╨├ ┬┴╙╔├, AS WELL AS MOST OTHER TYPES OF ┬┴╙╔├,  ARE
ALL VERSIONS OF ═ICROSOFT ┬┴╙╔├, THUS THE COMMANDS AND SYNTAX ARE VERY
SIMILAR.  ╘O TRANSFER THE LISTINGS FROM ONE MACHINE TO ANOTHER, THE
PROGRAM MUST BE FIRST SAVED AS AN ┴╙├╔╔ TEXT FILE ON THE ORIGINAL MACHINE.
(╘HE TOKENIZED PROGRAMS FOR THE VARIOUS ┬┴╙╔├S ARE NOT COMPATIBLE IN
BOTH FORMAT AND KEYWORD TOKENS.)  ╔N ╔┬═ AND ├╨/═ ┬┴╙╔├, THIS IS DONE
BY APPENDING AN ",┴" TO THE END OF THE ╙┴╓┼ STATEMENT:

      ╙┴╓┼ "FILENAME",┴

╔N ├-128 ┬┴╙╔├ 7.0, IT IS DONE USING THE FOLLOWING SEQUENCE OF STEPS
IN DIRECT MODE:

     ╧╨┼╬ 8,8,8,"0:FILENAME,S,W"
     ├═─8:╠╔╙╘
     ╨╥╔╬╘#8:├╠╧╙┼8

╘HIS FILE SHOULD BE READ IN BY ├╥╧╙╙ ╠╔╬╦ AS A ╙┼╤-╨┼╘╙├╔╔ FILE.
╬ON STANDARD CHARACTER CODES EMBEDDED IN PROGRAM TEXT (SUCH AS COLOR
CODES, REVERSE VIDEO AND CURSOR CONTROLS) SHOULD BE EDITED OUT, EITHER
BEFORE OR AFTER CONVERSION, BECAUSE THEY MAY CAUSE ╔┬═ AND ├╨/═ ┬┴╙╔├
TO BEHAVE IN ODD MANNERS.  ╘O LOAD AN ┴╙├╔╔ FILE WITH ╔┬═ OR ├╨/═ ┬┴╙╔├,
THE NORMAL ╠╧┴─"FILENAME" COMMAND IS USED.  ┴ ╙┼╤ TEXT FILE CAN ALSO
BE LOADED AS A PROGRAM ON THE ├-128.  ╘HIS IS DONE IN THE FOLLOWING
MANNER (MANY THANKS TO COLLEAGUE ╩IM ┬UTTERFIELD FOR DEMONSTRATING
THIS TRICK TO ME):

     ─╧╨┼╬ #1,"FILENAME"
     ╙┘╙ 65478,0,1
     ─├╠╧╙┼

(╔NCIDENTALLY, THIS IS NO MAGICAL ╥╧═ ROUTINE, BUT THE NORMAL ╦┼╥╬┴╠
├╚╦╔╬ FUNCTION AT HEX $╞╞├6 WHICH HAS BEEN ENHANCED ON THE 128.)
╘HE FILE TO BE READ IN SHOULD BE SAVED AS A ╙┼╤-┴╙├╔╔ FILE WITH ├╥╧╙╙
LINK.  ╘HIS ROUTINE READS IN THE TEXT FILE LISTING AND CONVERTS IT TO A
PROGRAM, JUST AS IF YOU HAD ENTERED EACH LINE DIRECTLY FROM THE KEYBOARD.
┬ECAUSE OF THIS, IT WILL NOT ERASE THE PROGRAM CURRENTLY IN MEMORY.  ╘HE
NEW PROGRAM WILL BE MERGED WITH ANY THAT IS CURRENTLY IN MEMORY.  ╔T
CAN THEREFORE ALSO BE USED TO MERGE TWO OR MORE ├-128 PROGRAMS.  ┘OU
MAY GET A "SYNTAX ERROR" OR "OUT OF DATA" MESSAGE AFTER THE PROGRAM
LISTING HAS BEEN READ IN.  ╘HIS IS CAUSED BY ANY EXTRANEOUS TEXT WHICH
MAY BE INCLUDED AT THE END OF THE LISTING FILE.  ╬ORMALLY, HOWEVER, IT
HAS NO EFFECT ON THE LOADING OF THE PROGRAM.  ╘HE FORMAT OF THE ┬┴╙╔├
LISTING IS IMPORTANT FOR FILES TO BE USED WITH ╔┬═ OR ├╨/═ ┬┴╙╔├.  ├-128
┬┴╙╔├ 7.0 DOES NOT REQUIRE SPACES BETWEEN KEYWORDS AND ARGUMENTS, WHILE
BOTH ╔┬═ AND ├╨/═ ┬┴╙╔├ DO.  ╞OR EXAMPLE, THE STATEMENT:

     10 ╞╧╥╔=1╘╧10

IS LEGITIMATE IN ┬┴╙╔├ 7.0.  ╞OR ╔┬═ AND ├╨/═ ┬┴╙╔├ IT MUST BE CHANGED
TO:

     10 ╞╧╥ ╔=1 ╘╧ 10

╔T IS ALSO IMPORTANT TO REMEMBER THAT THE NUMBER OF SIGNIFICANT CHARACTERS
IN ┬┴╙╔├ 7.0 VARIABLE NAMES IS LIMITED TO 2, WHILE BOTH ╔┬═ AND ├╨/═
┬┴╙╔├ HAVE NO SUCH RESTRICTION.  ╓┴╥╔┴┬╠┼1 AND ╓┴╠╒┼2 ARE DISTINCT
VARIABLE NAMES IN ╔┬═ AND ├╨/═ ┬┴╙╔├, WHILE IN ┬┴╙╔├ 7.0, THEY ARE BOTH
EQUIVALENT TO "╓┴".


╘HE MACHINE LANGUAGE PORTION OF THE PROGRAM IS A FILE NAMED "╪╠.═╠3" WHICH IS
AUTOMATICALLY LOADED BY THE MAIN PROGRAM.  ╘HE ═╠ ROUTINE, WHICH IS LOCATED
IN THE CASSETTE AND ╥╙ 232 BUFFERS, CONTAINS SEVERAL ENTRY POINTS.  ╘HESE
ARE:

┴S YOU CAN SEE, THERE ARE NO ╥┼═ STATEMENTS IN THE MAIN ┬┴╙╔├ PROGRAM.
┬ESIDE THE FACT THAT ╔ DON'T LIKE ╥┼═S (THEY CLUTTER UP THE

╘HE MAXIMUM FILE SIZE THAT CAN BE TRANSFERRED IN ANY DIRECTIONS IS 45.5
K BYTES.  ╠ONGER FILES WILL BE TRUNCATED TO THIS LENGTH.  ╘HIS IS
EQUIVALENT TO 183 ╙┼╤ BLOCKS OR NEARLY 3 FULL ├╨/═ DIRECTORY EXTENTS.
┴LL FILES IN MEMORY ARE ASSUMED TO BE IN ┴╙├╔╔ FORMAT.  ╙┼╤ FILES READ
WITH THE CONVERSION OPTION ARE ASSUMED TO BE ╨┼╘╙├╔╔ ON THE DISK AND
ARE TRANSLATED TO ┴╙├╔╔ AS THEY ARE READ IN.  ╙┼╤ FILES WRITTEN
WITH THE CONVERSION OPTION ARE ASSUMED TO BE ┴╙├╔╔ IN MEMORY AND ARE
CONVERTED TO ╨┼╘╙├╔╔ AS THEY ARE WRITTEN TO DISK.  ╙IMILARLY, CONVERSIONS
ARE MADE WHEN READING FROM OR WRITING TO ╨╥╟ SCREEN CODE FILES.  ┴LL
OTHER TRANSFERS ARE DONE IN A BINARY WHAT-YOU-SEE-IS-WHAT-YOU-GET FASHION.

├╥╧╙╙ ╠╔╬╦ CAN BE USED FOR SIMPLE ┴╙├╔╔ <> ╨┼╘╙├╔╔ CONVERSION OF ╙┼╤
FILES WITH EITHER A 1571 OR 1541 (OR OTHER COMPATIBLE ) DRIVE IN THE
FOLLOWING MANNER:

     ╨┼╘╙├╔╔ TO ┴╙├╔╔ - READ THE FILE IN ╨┼╘╙├╔╔ <> ┴╙├╔╔ CONVERSION
                        MODE, THEN WRITE IT IN BINARY MODE.

     ┴╙├╔╔ TO ╨┼╘╙├╔╔ - READ THE FILE IN BINARY MODE, THEN WRITE IT IN
                        ╨┼╘╙├╔╔ <> ┴╙├╔╔ CONVERSION MODE.

╧NE WORD OF CAUTION FOR ╨┼╘╙├╔╔ <> ┴╙├╔╔ CONVERSIONS.  ├╥╧╙╙ ╠╔╬╦ PASSES
CONTROL CODES (┴╙├╔╔ VALUE LESS THAN 32) AND CERTAIN OTHER SPECIAL
CODES THROUGH IN BOTH DIRECTIONS UNCHANGED.  ╔T ALSO ADDS A LINEFEED
CHARACTER (┴╙├╔╔ ├╚╥$(10)) AFTER EACH CARRIAGE RETURN WHEN CONVERTING
TO ┴╙├╔╔ AND REMOVES ALL LINEFEEDS WHEN CONVERTING TO ╨┼╘╙├╔╔.  ╘HE
PRESENCE OF THESE CODES IN, FOR EXAMPLE, TEXT FORMATTED ON A ├╨/═
WORD PROCESSOR MAY REQUIRE THE TEXT TO BE REFORMATTED WITH A ├-128
WORD PROCESSOR BEFORE IT CAN BE USED IN ├-128 MODE.  ╔N ADDITION,
DOCUMENTS ORIGINALLY WRITTEN OR EDITED WITH SOME WORD PROCESSORS
(SUCH AS ╫ORD╙TAR- EITHER ├╨/═ OR ╨├-─╧╙ VERSION) SHOULD BE HANDLED
IN NON-DOCUMENT MODE (I.E. STANDARD ┴╙├╔╔) ON THESE WORD PROCESSORS
IF THEY ARE INTENDED TO BE SUBSEQUENTLY USED IN ├-128 MODE.  ╫ORD╙TAR
SETS THE HIGH BITS IN THE LAST CHARACTER OF EACH WORD IN DOCUMENT
MODE.  ╘HIS RESULTS IN AN INCORRECT ┴╙├╔╔ TO ╨┼╘╙├╔╔ CONVERSION.  ╘HE HIGH
BIT CAN ALSO BE STRIPPED OUT USING THE ┌ OPTION (ZERO THE PARITY BIT) OF
├╨/═'S ╨╔╨ COMMAND TO COPY THE ORIGINAL FILE TO AN ┴╙├╔╔ COMPATIBLE FILE.
┴ SIMILAR ROUTINE CAN BE USED FOR CONVERTING BETWEEN ╙┼╤ AND ╨╥╟ TEXT
FILES.

╫HEN READING THE ╨├-─╧╙ DIRECTORY, ├╥╧╙╙ ╠╔╬╦ IGNORES THE FILE ATTRIBUTE
(BYTE 11) EXCEPT FOR THE VOLUME LABEL AND SUBDIRECTORY ATTRIBUTES WHICH
DO NOT REPRESENT VALID FILES.  ╘HUS YOU CAN DISPLAY AND ACCESS HIDDEN AND
SYSTEM FILES WHICH DO NOT SHOW UP ON AN ╔┬═-╨├ ─╔╥ COMMAND.  ├╥╧╙╙ ╠╔╬╦
SETS DIRECTORY BYTES 11-25 AND 30-31 TO 0 WHEN IT IS WRITING A NEW FILE.
╘HIS IS EASIER THAN TRYING TO CALCULATE A FILE CREATION TIME, DATE, ATTRIBUTE,
ETC.  ┌ERO BYTES IN THESE LOCATIONS ARE ACCEPTED BY ╨├-─╧╙.  ╞OR A MORE
DETAILED DESCRIPTION OF ╨├-─╧╙ FILE FORMATS, SEE ╨ART ╔ OF THIS ARTICLE.


├╥╧╙╙ ╠╔╬╦ WILL RECOVER UNUSED AND SCRATCHED DIRECTORY AND DATA SPACE FOR BOTH
├╨/═ AND ╨├-─╧╙ DISKS.  ╘HIS IS HANDLED AUTOMATICALLY BY ├OMMODORE ─╧╙ WHEN
WRITING TO ╙┼╤ OR ╨╥╟ FILES.  ├╥╧╙╙ ╠╔╬╦ IS CURRENTLY CONFIGURED TO WORK WITH
UP TO TWO DRIVES AND A PRINTER.  ╞OR ├╨/═ AND ╨├-─╧╙ FILES, AT LEAST ONE
OF THE DRIVES MUST BE A 1571.  ╘HE DEVICE CONFIGURATION CAN BE CHANGED
BY ALTERING THE DEFINITIONS OF ARRAYS ─╓() AND ─╓$() IN LINE 130-150.
╘O USE THE PRINTER FOR A FILE DUMP, SELECT ╙┼╤ ┴╙├╔╔ (FOR AN ┴╙├╔╔ PRINTER)
OR ╙┼╤ ╨┼╘╙├╔╔ AS THE TARGET FILE TYPE WITH THE "╙┼╘ ╘┴╥╟┼╘" OPTION
ON THE MAIN MENU.  (╘HERE IS NO NEED TO SPECIFY A FILENAME FOR THE
PRINTER. ┴ <RETURN> AT THE FILENAME PROMPT IS SUFFICIENT.) ┘OU CAN THEN
SELECT THE PRINTER AS THE TARGET DEVICE.   ╧F COURSE, THE 1541 OR
COMPATIBLE CAN ONLY BE USED TO READ OR WRITE ╙┼╤ OR ╨╥╟ FILES, SINCE IT DOES
NOT SUPPORT BURST MODE.

┴LTHOUGH IT IS NOT AN ╔┬═-╨├ EMULATOR, YOU WILL FIND ├╥╧╙╙ ╠╔╬╦ AN INVALUABLE
UTILITY FOR TRANSFERRING FILES FROM ONE MACHINE TO ANOTHER (AND BETWEEN
MODES ON THE ├-128 ALSO) IF YOU USE BOTH AN ╔┬═-╨├ AND A ├-128.  ╔T IS ALSO
POSSIBLE WITH A LITTLE DETAILED KNOWLEDGE OF THE DISK FORMATS TO USE THE
SAME PRINCIPLES FOR TRANSFERRING FILES TO/FROM OTHER COMPUTERS AND
OPERATING SYSTEMS THAT USE ═╞═ TYPE DISKS, SUCH AS ╘╥╙─╧╙ USED ON THE
╥ADIO ╙HACK COMPUTERS OR POSSIBLY ╥╙ ├O├O ╧╙/9 DISKS TO ╨┼╘ ╧╙/9 FORMAT.
