0.1.0          Shareware
_________________________________________________________________




0.1.1   The SHAREWARE Concept
_____________________________

   "Shareware" is a software distribution method which enables
   the potential user to obtain software at very low initial
   cost, for evaluation on a trial basis.

   You can evaluate the software in your own environment, on your
   own machine, with the programs and data that you normally use.
   You're not required to make payment and become a registered
   user unless the software meets your needs.

   Another benefit of Shareware is lower pricing.  By minimizing
   the marketing and advertising expenses associated with more
   traditional software distribution methods, Shareware products
   can be priced lower.  You don't pay for what you don't need or
   use.

   You are encouraged to share the evaluation version of this
   software with others, so long as you follow the limitations
   set forth in the LICENSE TERMS section below.




0.1.2   LICENSE TERMS
_____________________

   This product and its documentation are copyrighted and owned
   solely by the author, who reserves all rights to any benefits
   derived from it.  It is distinctly separate from, and should
   not be confused with, those categories of software known as
   "public domain" or "freeware."

   You are granted without charge a limited license to use the
   evaluation version of this software on a trial basis, for
   purposes of deciding whether to continue using (and therefore
   whether to register) the product, and to transmit this
   evaluation version to associates by copying on diskette or
   uploading to electronic bulletin board services, so long as
   the following CONDITIONS are met:

      (a) The program and its documentation file must be
          distributed together.

      (b) The program and its documentation must not be
          altered in any way.  If you wish to include
          notes for other evaluators, please add them in
          a separate file and include that file along
          with the program and documentation files.




0.1.3   REGISTRATION
____________________

      When you send in the registration form and fee, you'll
      receive by return mail a diskette containing the latest
      REGISTERED version of the program and documentation.


   BENEFITS OF REGISTRATION

      The registered version WILL NOT include the Evaluation Menu
      front-end or the forms-printing section of this version.
      Thus it will be more convenient to use, from either the DOS
      prompt or from batch files.  It will also be about 16K
      bytes smaller, for more efficient disk storage and faster
      loading.

      The registered version WILL include any new functions
      or enhancements made to date.

      You will receive notification of future updates and
      new products.

      You will be able to upgrade to newer versions at a
      reduced cost.


   REGISTRATION FORM

      The registration form and a pre-addressed mailing cover
      can be printed from the "Forms Printing" selection of
      the Evaluation menu, discussed in section 0.2.2 below.


   FEES

      The single-quantity registration fee is displayed on the
      initial Evaluation Menu screen.  Higher quantities are
      discussed below.


   QUANTITY DISCOUNTS

      Each registered copy of this software will be licensed for
      operation at only one location (on only one machine) at any
      one time.  If this software will be in use at more than one
      location at the same time, the appropriate number of
      registrations must be made.

      Multiple-quantity registration fees are displayed in the
      "QUANTITY DISCOUNT" section of the Evaluation menu.

      You can take advantage of quantity discounts by ordering
      multiple registrations of one program or single
      registrations of several different programs at the same
      time.  You also save on shipping and handling charges
      by registering several products together.


   GROUP REGISTRATIONS

      You can also get quantity discounts by combining orders with
      associates:

         (1)   Complete a separate registration form for each person.
                  Each person's name, address and programs to be
                  registered are needed for support and update
                  notification purposes.

         (2)   Include only one standard shipping and handling charge.
                  Cross out the "Shipping & handling" amounts on
                  all but one registration form; the combined
                  order will be sent to the name and address on
                  that form.

         (3)   Send all the forms together in one envelope or mailing
                  cover, with a single check or money order.




_________________________________________________________________

0.2.0          Evaluation
_________________________________________________________________




0.2.1   EVALUATION VERSION
__________________________

   This software contains the complete and fully functional version
   of the program, the latest available at the time of this release.

   The program itself is identical to the REGISTERED version.
   An Evaluation Menu and forms-printing section were added
   to ensure that:

      (a)   Registration information and forms will not
            become separated from the program file.

      (b)   Users who might be unfamiliar with the process
            of displaying a file's contents on the screen or
            printer will have no difficulty learning about,
            evaluating or registering this product.




0.2.2   EVALUATION MENU
_______________________

   The program is invoked from the DOS prompt by typing its name
   and pressing the RETURN or ENTER key.


   The initial screen displays the warranty section and some
   information about the program:

      Program name,
      Version number,
      Release date,
      Single-quantity registration fee.


   It next displays the Shareware Product EVALUATION MENU.
   A single key press will select the following functions
   from the menu:
      _________________________________________

      ESC - EXIT to DOS without evaluating this program

       R  - READ the documentation (THIS file)

       x  - EVALUATE this program

       Q  - QUANTITY Discount information

       F  - FORMS printing menu - registration & mailer
      _________________________________________


   When you press "R" to READ the documentation, this file will
   be shown one screen at a time.  The display pauses whenever the
   screen becomes full, and prompts...

                     <downArrow> or Esc

   The <downArrow> character is similar to the "MORE" prompt in
   other DOS utilities.  It indicates that more is available.
   Press ESCape to exit back to the Evaluation Menu, or any normal
   typing key to continue (space bar is a convenient key to use).




0.2.3   VIRUS PREVENTION
________________________

   If you'd like to evaluate this software but you're not sure
   where it's been, you can get a copy straight from the source
   for a $4.00 charge to cover the cost of the diskette, shipping
   and handling.  If your address is outside the U.S. and Canada,
   add an additional $3.00 (total $7.00, in U.S. funds).

   Include your mailing address and the name of the program.
   By return mail you'll receive the latest evaluation version
   of that program and as many others as will fit on a 5.25
   inch diskette.

               SPLIT
1.0
               File Splitter Utility
______________________________________________________________




1.1   INTRODUCTION
__________________

   You have a large text file to be edited (or just to be read).
   Some word processors/text editors will handle any file size, as
   long as the file can fit on a disk.  Others handle only files
   that will fit into free memory.  Still others are specifically
   designed for a certain maximum file size.

   Once you get the file into your editor, you can edit it down
   into smaller files.  But it's so big that it won't all load
   into the editor.

   Or maybe it's too big to fit on a single diskette, but you need
   to save it in an easily readable form (thus precluding the use
   of the DOS BACKUP/RESTORE utilities).


   SPLIT it.




1.2   EXPLANATION
_________________

   SPLIT reads a specified file and writes the contents into
   several smaller files.  Currently, it splits a file into
   two others, each half the size of the specified file.
   The original file is preserved.

   SPLIT's primary purpose is to process text files, but it
   will handle any file type that can be specified on the
   command line.

   The division is made at the 50% boundary without regard
   to contents.  It may occur within a word, sentence or
   paragraph.


   SPLIT will refuse to process files containing zero bytes.
   It also refuses to accept input files with extensions of
   ".01" or ".02", since these extensions are used for the
   output files.  For further explanation, see the ERROR
   MESSAGE section.




1.3   SYSTEM REQUIREMENTS
_________________________

   PC, XT, AT or compatible.
   DOS version 2.1 or later.
   80K free memory.




1.3.1   INSTALLING
__________________

   The program can be run from diskette or from hard disk.
   No installation is necessary, other than copying the files
   to a drive and directory of your choosing.




1.4   HELP
__________

   Can't remember the command line syntax?
   Issue the program's name without any parameters; it
   will display a help screen, then return to the DOS prompt.




1.5   SYNTAX
____________


      SPLIT [filespec]


         Where [filespec] is the string needed to reference a file;
         can also be shown as [d:][path][filename.ext].

         The minimum filespec needed is filename.ext.  If the file
         is in another directory and/or on another drive, the
         drive name and/or path name must also be given.

         The complete filespec for a file named ThisFile.Doc
         residing in drive A: in a subdirectory named ThisSub is

               A:\ThisSub\ThisFile.Doc

         For further information on filespecs, see your DOS manual.




1.6   EXAMPLES
______________

      SPLIT Myfile.Doc

         Reads the file named Myfile.Doc, if it is found in the
         current drive and directory (otherwise displays an error
         message and returns to DOS).  Creates two new files,
         Myfile.01 and Myfile.02, in the current drive and
         subdirectory.  Each of the new files is half the size
         of the original.  Myfile.Doc is preserved.


      SPLIT A:\SomeDir\YourFile.Doc

         Reads the file named YourFile.Doc, if found in the
         specified subdirectory of the specified drive.
         Creates two new files, YourFile.01 and YourFile.02,
         in the current drive and directory.  Again, each is
         half the size of the original.




1.7   APPLICATIONS
__________________


   Borland's SideKick version 1.5 includes a pop up notepad that
   will handle up to 45,000 characters (45Kbytes), or 50Kb if you
   omit the calendar function.  The notepads in SideKick's newer
   incarnation, SideKick PLUS, will handle up to 54Kb each.

   These and other memory-resident notepad utilities are extremely
   useful, since you can use them from within other programs.

   Example:

      You have a complex payroll (or general ledger or
      spreadsheet) program.  When you first learned how to
      use it, you ferreted out the important notes and
      examples in the manual and typed them into a file you
      named "PRnotes.Doc" (or GLnotes.Doc or SSnotes.Doc).

      Now, whenever you're in the midst of running payroll
      and need some information, you can pop up your memory-
      resident notepad, load PRnotes.Doc, and use the search
      function to look for particular keywords.  Much faster
      than manually looking through a book or returning to
      DOS to read your note file.  You can also import text
      or sample data from the program screens into the
      note file for future reference.


      The time will come, however, when you've added so many
      notes and imported so many screens that PRnotes.Doc
      will no longer load into the pop up notepad.

      Instead of suddenly having to do without your online
      notes and sample data, you can SPLIT the file:

               SPLIT PRnotes.doc

      creates two new files half the size of the original:

               PRnotes.01
               PRnotes.02

      You could leave the names of the new files as they
      are, or rename them to

               PRnote1.Doc
               PRnote2.Doc

      Now you're back in business.  If the files later grow
      too large, split them again.



   If you frequent electronic bulletin board systems (BBS's), you
   can build some very large text files on disk.  Using "nonstop"
   mode, hundreds of messages can be downloaded in a short amount
   of time.  With your communications software's "capture" or
   "logfile" feature enabled, the messages will all be recorded in
   a file on disk.  This not only saves phone charges, but allows
   more users access to the BBS.

   When you go offline and try to edit this sometimes huge capture
   file, your editor may choke on it.  SPLIT it into digestible
   sections.




1.8   ERROR MESSAGES
____________________

      Insufficient disk space to continue.

      <filename.ext> - input file not found.

      <filename.ext> - size is 0 bytes; cannot split.

      <filename.ext> - extension reserved for output - rename.

         If an input file extension of ".01" were allowed, and
         a valid file named "MyFile.01" were entered on the
         command line, that file would quickly disappear!
         After some initial validation checking, SPLIT creates
         two new output files, using the filename of the input
         file and extensions .01 and .02. Creation of the new
         output file "MyFile.01" would overwrite the input
         file; SPLIT would then hang, trying to read from a
         zero-length file.


      Cannot open input file <filename.ext>

      Cannot create output file <filename.nn>




1.9   FUTURE ENHANCEMENTS
_________________________

   The current version of SPLIT divides an input file into only
   two parts.  A future version will allow you to specify the
   number of parts.




2.0   VERSION HISTORY
_____________________

   1.00  Initial release.




_________________________________________________________________

9.0            Support
_________________________________________________________________




9.1   PROBLEM RESOLUTION
________________________

   Please document and report any anomaly in program operation,
   whether it's a genuine "bug" or just some feature of the
   program that particularly "bugs" you.

   If you're the first person to document and report a problem
   that we agree needs attention, you'll receive a free upgrade
   with the correction when it's been made.  If you're a
   registered user, you'll get the upgraded registered version;
   if you haven't yet registered, you'll get the upgraded
   evaluation version.




9.2   BEFORE REPORTING
______________________

   Things to try prior to reporting a problem:

      1 - Reread the documentation to make sure you understand
          what we thought we understood when we wrote it.

      2 - If the system reports "Bad command or file name" when
          you attempt to run the program, its executable file
          (or at least the file name you specified) was not found.

          First, make sure no typos or misspellings have crept
          into your command line; next, try changing your PATH
          setting, or make the drive & directory where the program
          resides the "current" drive & directory.

      3 - If the program is being run from a batch file, try
          deleting lines previous to the line that actually
          invokes the program, to see if some prior activity
          is causing the problem.

      4 - If you have any memory-resident or "TSR" utilities
          installed (pop-up calculators/note pads, keyboard
          enhancements, etc.), try removing them from memory
          and running the program again to see if the problem
          reoccurs.




9.3   REPORTING A PROBLEM
_________________________

   If the problem persists, please document it as completely and
   accurately as possible; we have to be able to duplicate it
   before we can begin to resolve it.

   Include at least the following:

      1 - Version of DOS you are using.
      2 - Machine type, drives, memory, etc.
      3 - Programs executed prior to the problem.
      4 - Problem program's name and version number.
      5 - Where and how you obtained the problem program.
      6 - Address and/or phone number where you can be contacted.
      7 - Anything you can think of that might relate to the problem;
          for example, listings of your AUTOEXEC.BAT and CONFIG.SYS
          files, or any batch files used to run the program.
      8 - Any relevant printouts.


   NOTE: If you're a registered user, you'll find the utility
         UserResp.Exe on the distribution diskette; it can be used
         to print a pre-addressed mailer and a problem report.

         If you have not yet registered, send problem reports to the
         address below (or print the pre-addressed mailer from the
         Evaluation Menu).
