╟┼╧╓╔┼╫┼╥ BY ╙IAMAK
╞OR ├ 64
╘HIS PROGRAM ALLOWS YOU TO VIEW/PRINT ╟┼╧╨┴╔╬╘ FILES WITHOUT ╟┼╧╙. ╔T WORKS
WITH BOTH STRAIGHT ╟┼╧╨┴╔╬╘ FILES AND CONVERTED ╟┼╧╨┴╔╬╘ FILES.
╘HE PROGRAM IS MENU DRIVEN AND EASY TO USE.
╬OTE FOR THOSE UNFAMILIAR WITH ╟┼╧╨┴╔╬╘ FILES: ╘HESE FILES HAVE A FORMAT WHICH
IS SIMILAR TO, BUT NOT QUITE LIKE, A RELATIVE FILE. ╘HEY CAN NOT BE COPIED
(WITHOUT ╟┼╧╙) OR TRANSMITTED VIA A MODEM. ├ONVERTED FILES ON THE OTHER HAND,
LOOK LIKE REGULAR ├OMMODORE FILES, EITHER ╙┼╤ OR ╨╥╟ TYPE. ╘HEY CONTAIN ALL
THE INFORMATION OF THE ORIGINAL ╟┼╧╨┴╔╬╘ FILE. ╞OR THE PURPOSE OF USING WITH
THIS PROGRAM, THE CONVERTED FILES NEED NOT BE CHANGED BACK TO ╟┼╧╨┴╔╬╘ FORMAT.
-------------------------------------------------------------------------------
═AIN ═ENU
╫HEN YOU LOAD AND RUN THE PROGRAM, YOU WILL BE IN THE ═AIN ═ENU. ╔N THE BOX
AT THE BOTTOM OF THE SCREEN THE CURRENT SETUP OF THE PROGRAM IS DISPLAYED.
╘HESE ARE SET TO DEFAULT VALUES AT THE START.
┘OU HAVE THREE CHOICES IN THE ═AIN ═ENU: ╠OAD AND VIEW A ╟┼╧╨┴╔╬╘ FILE, CHANGE
PROGRAM SETUP, OR QUIT. ┼ACH ONE IS SELECTED BY A FUNCTION KEY.
-------------------------------------------------------------------------------
╙ETUP ═ENU
╫HEN YOU SELECT '├HANGE ╙ETUP' FROM THE ═AIN ═ENU, YOU WILL BE TAKEN TO THE
╙ETUP ═ENU. ╚ERE YOU CAN CHANGE THE PROGRAM SETUP.
┘OU CAN TOGGLE FAST LOADER ON OR OFF, CHANGE ╙OURCE AND ╙AVE DRIVE NUMBERS, OR
CHANGE THE PRINTER.
╬OTE THAT ╙OURCE DEVICE IS THE DRIVE FROM WHICH FILES ARE LOADED, EITHER ╟┼╧-
╨┴╔╬╘ FILES OR PRINTER DRIVERS.
╙AVE DEVICE IS USED ONLY FOR SAVING BITMAP SCREEN (SEE ─ISPLAY ═ODE).
╔F YOU ARE USING ONE DRIVE SYSTEM, THEN BOTH ╙OURCE AND ╙AVE DEVICE NUMBERS
SHOULD BE THE SAME.
╘HE PROGRAM WORKS WITH 1541/1571/1581 DRIVES (1571 IN 1541 MODE). ╚OWEVER,
ON 1581 IT DOES NOT SUPPORT PARTITIONED DISKS.
├HANGING PRINTER: ╘HE PROGRAM HAS TWO BUILT-IN PRINTER DRIVERS, ├OMMODORE
1525/801 AND ┼PSON, PLUS AN OPTION FOR LOADING EXTERNAL DRIVER.
╔F YOU CHOOSE THE THIRD OPTION, THEN YOU MUST SUPPLY THE PRINTER DRIVER. ╞OR
THE STRUCTURE OF THE PRINTER DRIVER SEE THE ACCOMPANYING FILE "─╥╔╓┼╥.╞╧╥═┴╘".
╬OTE ON THE FAST LOADER: ╘HE FAST LOADER IS PROVIDED FOR CONVENIENCE AND IS
FOR 1541 DRIVES ONLY. ╔T MAY NOT WORK PROPERLY ON NON-COMPATIBLE DRIVES OR
DRIVES WHICH ARE NOT IN PERFECT ALIGNMENT. ╔F YOU SEE THAT THE FAST LOADER
DOES NOT WORK PROPERLY ON YOUR DRIVE, THEN TOGGLE IT OFF. ╔T WILL BE SLOWER
BUT SURER.
╘HE PROGRAM ALSO SUPPORTS ╥┼╒ (╥AM ┼XPANSION ╒NIT). ╬O ╥┴═─╧╙ UTILITY NEED BE
INSTALLED, THE PROGRAM HANDLES ╥┼╒ DIRECTLY.
-------------------------------------------------------------------------------
╓IEWING ╟┼╧╨┴╔╬╘ FILES
╫HEN YOU SELECT '╠OAD & ╓IEW ╞ILE' OPTION FROM THE ═AIN ═ENU, YOU WILL BE
ASKED TO INSERT DISK WITH ╟┼╧╨┴╔╬╘ FILE. ╘HE DISK DIRECTORY WILL BE READ AND
DISPLAYED IN A MENU. ╙ELECT THE FILE AND THE PROGRAM WILL BEGIN TO LOAD THE
FILE.
╬OTE THAT THE INITIAL LOAD OF A CONVERTED FILE TAKES LONGER THAN THE SAME FILE
IN ORIGINAL ╟┼╧╨┴╔╬╘ FORMAT, SINCE THE PROGRAM HAS TO SET UP THE INDEX TABLE
"MANUALLY" FOR THE CONVERTED FILES.
╔F ╥┼╒ IS PRESENT, THE INITIAL LOAD WILL STILL BE LONGER SINCE THE ENTIRE FILE
IS READ AND STORED AT THE BEGINNING. ╘HIS SPEEDS UP SCROLLING IN DISPLAY MODE
CONSIDERABLY.
╔F ALL GOES WELL THE PROGRAM SWITCHES TO THE DISPLAY MODE. ╔F ANY ERROR OCCURS
(SEE ┼RROR ═ESSAGES), YOU WILL BE RETURNED TO THE FILE DIRECTORY MENU.
-------------------------------------------------------------------------------
─ISPLAY ═ODE
╘HE ├ 64 SCREEN WILL BE INITIALLY AT THE UPPER LEFTMOST CORNER OF THE ╟┼╧-
╨┴╔╬╘ FILE. ┴T THE BOTTOM OF THE SCREEN A COMMAND BAR IS DISPLAYED WITH THE
LIST OF THE ACTIVE COMMANDS IN DISPLAY MODE.
╘HE COMMAND BAR CAN BE TOGGLED ON OR OFF AT ANY TIME BY PRESSING ╞1 KEY.
╔N DISPLAY MODE THE FOLLOWING COMMAND KEYS ARE USED:
1) ├URSOR KEYS: ╘HESE WILL MOVE THE 64 SCREEN RELATIVE TO THE ╟┼╧╨┴╔╬╘ FILE IN
THE APPROPRIATE DIRECTION,I.E., LEFT, RIGHT, UP OR DOWN. ╘HE MOVEMENT IS 8
PIXELS IN EITHER DIRECTION: ONE BYTE HORIZONTALLY, ONE ROW VERTICALLY.
2) ╘, ┬, ╠, ╥, ├: ╘HESE KEYS ARE USED TO MOVE QUICKLY TO THE TOP, BOTTOM, LEFT
, RIGHT OR CENTER OF THE ╟┼╧╨┴╔╬╘ FILE, RESPECTIVELY. ╬OTE THAT "QUICKLY"
MEANS YOU CAN GET TO THOSE AREAS USING ONE STEP COMMANDS, RATHER THAN STEP
BY STEP WITH CURSOR KEYS. ╘HE PROGRAM HAS STILL TO LOAD DATA FOR THE NEW
REGIONS, EXCEPT WHEN ╥┼╒ IS INSTALLED.
┘OU WILL HEAR A BELL SOUND WHEN YOU REACH THE BOUNDARIES OF THE ╟┼╧╨┴╔╬╘ FILE.
3) ╙: ┘OU CAN SAVE THE CURRENT BITMAP SCREEN AS A ─╧╧─╠┼ FILE BY PRESSING THE
"╙" KEY AT ANY TIME. ┘OU WILL THEN BE ASKED TO SUPPLY A FILE NAME FOR SAVE.
╘HE FILE WILL BE SAVED TO THE DISK IN THE DRIVE DESIGNATED AS ╙AVE DEVICE.
╬OTE THAT THE PREFIX "──" WILL BE ADDED TO THE FILE NAME BEFORE SAVING.
┴LSO NOTE THAT THE FULL 320X200 PIXELS SCREEN WILL BE SAVED. ╘HE COMMAND
BAR, IF IT IS ON THE SCREEN, WILL BE REMOVED AND REPLACED WITH APPROPRIATE
DATA BEFORE SAVING.
4) ╨: ╨RESS "╨" KEY IF YOU WISH TO PRINT THE FILE YOU ARE VIEWING. ═AKE SURE
THE PRINTER IS ON AND THE APPROPRIATE PRINTER DRIVER IS IN PLACE.
╘HE PRINT STARTS AT THE BEGINNING OF THE ╟┼╧╨┴╔╬╘ FILE. ╔T DOES NOT MATTER
WHERE THE BITMAP SCREEN IS (RELATIVE TO THE ╟┼╧╨┴╔╬╘ FILE) AT THE TIME.
╬OTE THAT WITH THE 1525/801 COMPATIBLE PRINTERS YOU ONLY GET 480 DOTS OF
THE 640 DOTS (HORIZONTALLY) OF THE ╟┼╧╨┴╔╬╘ FILE. ╘HE BUILT-IN ┼PSON
PRINTER DRIVER, HOWEVER, PRINTS THE FULL PAGE AT 80 ─╨╔.
5) <╥┼╘╒╥╬>: ╚IT THIS KEY WHEN YOU ARE DONE AND WANT TO LOAD A NEW FILE.
╘HE PROGRAM ACCESSES THE DISK REPEATEDLY WHILE IN DISPLAY MODE (UNLESS ╥┼╒ IS
INSTALLED), SO LEAVE THE DISK WITH THE FILE YOU ARE CURRENTLY VIEWING IN THE
╙OURCE DRIVE. ╧NLY CHANGE THE DISK WHEN THE PROGRAM INSTRUCTS YOU TO.
-------------------------------------------------------------------------------
┼RROR ═ESSAGES
╘HE PROGRAM HAS A RATHER EXTENSIVE ERROR CHECKING. ╚OWEVER MAKE SURE ALL DISKS
AND FILES ARE IN PROPER CONDITION AND THE RIGHT DISK IS IN THE RIGHT DRIVE.
╘HE ERROR COULD ALSO BE BECAUSE THE FAST LOADER IS NOT FUNCTIONING PROPERLY,
IF IT IS ON. ╔N THIS CASE USE NORMAL LOAD AND TRY THE SAME DISK AND FILE. ╔F
THE ERROR PERSISTS IN THE SAME PLACE, THEN THERE IS SOMETHING WRONG WITH THE
DISK AND/OR THE FILE.
┴SIDE FROM NORMAL ─╧╙ MESSAGES, YOU MIGHT SEE TWO OTHER ONES. ╘HEY ARE:
1) "╫RONG FILE FORMAT" - ╘HIS MESSAGE APPEARS WHEN THE FILE YOU HAVE SELECTED
IS NEITHER A ╟┼╧╨┴╔╬╘ FILE NOR A CONVERTED ONE. ╘HE PROGRAM LOOKS FOR
HEADER INFORMATION, AND IF IT DOES NOT FIND IT, IT WILL NOT RECOGNIZE THE
FILE.
2) "╔NVALID DATA, RECORD **" - ╟┼╧╨┴╔╬╘ FILES ARE CODED. ╘HE DATA IS DECODED
WHEN READING. ╔F THE DATA READ IS INCOMPATIBLE WITH THE CODING SCHEME, THEN
THIS MESSAGE RESULTS. ╔T IS FOLLOWED BY A NUMBER, FROM 0 TO 44, WHICH IS
THE NUMBER OF THE ╟┼╧╨┴╔╬╘ RECORD IN WHICH THE ERROR OCCURED.
╔N EITHER OF THESE TWO CASES CHECK THE FILE, ASSUMING THE SAME ERROR OCCURS
IN THE SAME PLACE WITH FAST LOADER OFF.
-------------------------------------------------------------------------------
╘HIS PROGRAM IS SHAREWARE. ╔F YOU FIND IT USEFUL PLEASE SEND A CONTRIBUTION OF
$5 TO THE ADDRESS BELOW. ├OMMENTS ARE ALSO WELCOME.
