Date: Sun Dec 24 19:48:27 1989


                                   CHAPTER 3
     
     
                      USING THE DOS 2 UTILITIES (DUP.SYS)
     
     
     If you boot a DOS disk with no cartridge in the slot or with BASIC
     disabled (by holding the OPTION key), DOS will try to load the file
     named DUP.SYS.  This is the disk utility file.  When using BASIC,
     typing DOS [RETURN] will load the DUP.SYS file.  When the utilities
     are loaded the menu will appear on the screen.

     SELECT ITEM OR [RETURN] FOR MENU
     
     
     [A] DIRECTORY
     
     After pressing [A] [RETURN] you will get the prompt:
     
      DIRECTORY--SEARCH SPEC,LIST FILE?
     
     If you want to see the entire directory just press [RETURN] again.  If
     you wish, you may type in a specific file name (D: is optional) or
     wild cards to search for.  If you specify a search spec only matching
     files will be displayed.
     
     If you want, you can have the directory sent to another device.  To do
     this type a comma and the device name.  For example, if you type ,P:
     the directory will be sent to the printer.
     
     [B] RUN CARTRIDGE
     
     If a cartridge was inserted or BASIC was not disabled when the
     computer was turned on, [B] [RETURN] will run that cartridge or
     BASIC.
     
     [C] COPY FILE
     
     This option will copy a file to another part of the same disk (with a
     different file name) or copy from one disk drive to another.  When you
     press [C] [RETURN] you will be given the prompt:
     
      COPY--FROM,TO
     
     Type the devices and file names separated by a comma.
     
     
                                   EXAMPLES:
     
                                FOREMAN,FIREMAN
     
                                      or
     
                                D1:TEST,D2:TEST
     
     
     The first example will copy to the same disk.  The second example will
     copy from disk drive one to disk drive two.
     
     If you want to have the first file appended to the end of the second
     file type /A after the file names.
     
     
                                   EXAMPLE:
     
                           RUNMENU.EXE,AUTORUN.SYS/A
     
     
     If the files are binary load files, this will cause both files to be
     saved as one file.  When the load command is used they will both be
     loaded and run.
     
     [D] DELETE FILE(S)
     
     After pressing [D] [RETURN] you will get the prompt:
     
      DELETE FILE SPEC
     
     After typing the file name you will be asked to confirm the file to
     delete.
     
      DELETE FILE SPEC
      DELETE-D1:JUNK ARE YOU SURE?
     
     Press [Y] if the correct file is displayed.  If you use wild cards you
     will be asked to confirm each matching file.
     
     [E] RENAME
     
     Upon typing [E] [RETURN] you will be given the prompt:
     
      RENAME-GIVE OLD NAME,NEW

     Type the file name you want to change and the new name separated by a
     comma.
     
     
                                   EXAMPLE:
     
                                  COLT,HORSE
     
     
     WARNING!  Do not rename a file to a name which already exists on the
     disk.  You will end up with a duplicate file name and will not be able
     to access one of them.  Attempting to rename or delete one of them
     will rename or delete both.  The only way to fix a duplicate file name
     is with a sector editor or other special utility.
     
     [F] LOCK FILE
     
     A locked file cannot be written to, renamed or deleted.  To lock a
     file type [F] [RETURN].  You will get the prompt:
     
      WHAT FILE TO LOCK?
     
     Type the file name you want to lock.  Wild cards will cause all
     matching files to be locked.
     
     [G] UNLOCK FILE
     
     Used the same as lock.
     
     [H] WRITE DOS FILES
     
     This option will write the DOS.SYS and DUP.SYS files to a formatted
     disk.  When you type [H] [RETURN] you will receive the prompt:
     
      DRIVE TO WRITE DOS FILES TO?
     
     Type the number of the drive.  If the drive contains a formatted disk
     the dos files will be written to it.
     
     [I] FORMAT DISK
     
     This option formats a new disk or erases a disk with files on it. 
     Typing [I] [RETURN] will get you the prompt:
     
      WHICH DRIVE TO FORMAT
     
     Be sure you have the correct disk in the proper drive then type the
     drive number.  It is impossible to recover files on a disk formatted
     by accident.
     
     While the disk is being formatted the drive will check to be sure the
     disk is formatted correctly.  If not, the drive attempt to format the
     disk again.  If the disk is defective the drive will not finish the
     formatting process.
     
     [J] DUPLICATE DISK
     
     This option will copy an entire disk except for sectors listed as free
     in the VTOC.  Some programs are copy-proofed by changing the VTOC to
     show that some occupied sectors are empty.  For such disks, a program
     which copies the entire disk is needed.
     
     When you press [J] [RETURN] you will be given the prompt:
     
      DUP DISK--SOURCE,DEST DRIVES?
     
     If you are using only one disk drive, type 1,1.  If you have only one
     drive you will be told when to swap disks.
     
     [K] BINARY SAVE
     
     This option saves a block of memory as a binary load file.  When you
     type [K] [RETURN] you will be given the prompt:
     
      SAVE-GIVE FILE,START,END(,INIT,RUN)
     
     Type the desired file name and a comma.  Now type the start and end
     addresses of the memory block to be saved, in hexadecimal numbers,
     separated by commas.  If the file is a program which is to
     automatically run when loaded, give the initialization address, if
     needed, then the run address.
     
                                   EXAMPLE:
     
     
                           CHASE.EXE,0700,09FF,,0700
     
     
     This will save the block of memory from address 0700 to 09FF.  The
     program is not initialized before running so there is no address typed
     after the third comma.  When the program is loaded the computer will
     jump to address 0700, as specified in the last parameter, to run the
     program.
     
     [L] BINARY LOAD
     
     To load a binary file type [L] [RETURN]. You will get the Prompt:
     
      LOAD FROM WHAT FILE?
     
     Type the file name and the file will be loaded.  If wild cards are
     used, only the first matching file will be loaded.
     
     [M] RUN AT ADDRESS

     Typing [M] [RETURN] will get the prompt:
     
      RUN FROM WHAT ADDRESS?
     
     Type the hexadecimal address of the program you want to run.
     
     [N] CREATE MEM.SAV
     
     A MEM.SAV file is used by BASIC and some other programs to save the
     part of memory which the DUP.SYS file loads into.  If there is no
     MEM.SAV file on the disk when you go to the DOS utilities, you will
     loose that part of memory.  With BASIC you will loose your program.
     
     When you type [N] [RETURN] you will get the prompt:
     
      TYPE Y TO CREATE MEM.SAV
     
     Typing [Y] [RETURN] will create a MEM.SAV file on the disk in drive
     one.
     
     [O] DUPLICATE FILE
     
     This option is used to copy a file from one disk to another, using
     only one disk drive.  When you type [O] [RETURN] you will get the
     prompt:
     
      NAME OF FILE TO MOVE?
     
     If you use wild cards you will be asked to swap disks for each
     matching file.
     
     
     DOS 2.5 also has option:
     
     [P] FORMAT SINGLE
     
     DOS 2.5 normally formats disks to use "enhanced" density.  This option
     will format a disk in single density for use with the 810 drive.
     
     DOS 2.5 also has some special utilities on the master disk.  Use the
     binary load option to run them.
     
     RAMDISK.SYS
     
     This program will cause the extra bank of memory in the 130XE to act
     like a disk drive (called D8:).  If this program is on the disk it
     will automatically run.  It need not be renamed to AUTORUN.SYS.
     
     COPY32.COM
     
     Copies DOS 3 files to DOS 2.
     
     DISKFIX.COM
     
     Can make certain "repairs" to a disk, such as restoring deleted
     files.
     
     SETUP.COM
     
     Used to change the default configuration of DOS.
     
     AUTORUN.SYS (DOS 2.0 and 2.5)
     
     This program is needed to operate the RS-232 ports on the 850
     interface.  If you don't want this program to automatically load when
     you boot with the master disk, rename the file to RS232.
     
     SPECIAL DOS INFORMATION
     
     When DOS is in memory, changes can be made to the DOS program.  These
     changes can be made by poking the changes into memory.  If you want to
     make the changes permanent, you can type DOS [RETURN] to load the
     utilities.  From the utilities menu you can use the write DOS files
     option to save the changes on disk.  Some of the useful changes you
     can make follow.
     
     
      POKE 1913,80
     
     This turns off the write verify and speeds up disk writing.
     
     
      POKE 1913,87
     
     This turns write verify on
     
     
      POKE 5903,42
      POKE 5904,46
      POKE 5905,82
      POKE 5906,85
      POKE 5907,78
      POKE 5908,155
     
     This causes any binary file with the extender .RUN to be loaded
     automatically when the computer is turned on.
     
     
      POKE 5903,65
      POKE 5904,85
      POKE 5905,84
      POKE 5906,79
      POKE 5907,82
      POKE 5908,85
     
     This returns the DOS to normal, Automatically loading files named
     AUTORUN.SYS.
     
     
         DOS 2.0            DOS 2.5
     
                         POKE 3772,255
      POKE 3818,64       POKE 3774,64 
      POKE 3822,123      POKE 3778,123
     
     This will cause DOS to accept lower-case as well as upper-case letters
     in file names.  It will also now accept @,[,\,],^ and _ .
     
     
                         POKE 3772,223
      POKE 3818,65       POKE 3774,65 
      POKE 3822,91       POKE 3778,91 
     
     This will change DOS back to normal, accepting only upper-case letters
     and numbers.
