There are 20  files on your installation  disk. The two files  SMLMODEL.MDL and
POWERMAK.EXE will  be  placed in  a  directory on  your  DOS search  path.  The
remainder  of  the  files  may be  placed  in  any  directory  you desire.  The
POWERBAT.DOC file is the documentation and  may be viewed with any text  editor
or printed to  your printer with the  DOS print command (ie  print POWERBAT.DOC
<enter>). The files with  an extension of .PWR are PowerBatch  source files and
the text  is printed  in the  documentation. You  should compile  these example
files  and  run  the  resulting  programs  to help  familiarize  yourself  with
PowerBatch.  The  file  DEMO1.PWR  uses  all  the  commands  with a  couple  of
exceptions.

To install PowerBatch  run the install program  located on the source  disk. If
the source in on a floppy drive enter A:PBINSTAL (or B:PBINSTAL). If the source
is on  a hard drive, change directory to  the directory containing PBINSTAL and
enter

   PBINSTALL <enter>

If you have purchased a registered copy of PowerBatch, the install program will
recognize this  by the presence  of REGISTER.EXE  on your  diskette. When  this
program is  present, the  copy of PowerBatch  you have  just installed  will be
registered in your name.

Your  name  and  serial  number  will  be  imbedded  in  the  software  by  the
registration program. If you give  anyone an evaluation copy of PowerBatch,  DO
NOT PROVIDE THE REGISTRATION PROGRAM WITH THE EVALUATION COPY. Simply  copy all
of  the files but REGISTER.EXE. Better still, compile the two PowerBatch source
files  PBCLONE.PWR  and  MOVESUB.PWR  and  use  these  to  create  a  clone  of
PowerBatch. PBCLONE uses  MOVESUB as a subroutine and is an  example of the use
of  subroutines  in  PowerBatch.  Anyone  who  uses  the  registration  program
REGISTER.EXE will imbed your name and serial number within their software.

                                 Change Record
V1.0-1.3 were alpha and beta test versions not available to the public.
V1.4    Added BreakOn, BreakOff, and ?EnvStr commands.

        Fixed bug in keyboard input routine which was incorrectly handling a
        single keystroke.

        Changed execution of DOS commands to prevent loading of another copy of
        command processor.

        Changed beep command to default to 1 repetition.

V1.4a   Added SetPath, Prompt, and SetEnv commands to allow changing of
        environment variables in the master and current environment.

V1.4b   Rewrote the routine which gets another output file name if the default
        name is not acceptable.

V1.4c   Fixed bug in SetVar command which was damaging the path environment
        variable in the current environment area.

        Added error messages to commands which set environment variables in
        both current and master environment areas if the environment area was
        not found or the change or addition exceeded the amount of free space
        available in the environment area.

        Fixed bug which was truncating the POWERBAT.ERR file if fatal compile
        errors existed.

        Enabled stdout redirection from within PowerBatch. ie Pgmname > nul

V1.4d   Added special character indicator to READKEY command.

        Added ADD and SUBTRACT commands. Provides a means to loop N times.

V1.4e   Added ability to escape from routine which prompts user for valid input
        source file name if none is given or an error is detected.

        Characters which are not on the keyboard may be defined using the
        decimal value of the character ie "Variable Enter,2,#17#217"

        Added the ability to define color changes within a stream of text. The
        trigger character is Ctrl-A and this is followed by the THREE digit
        color attribute. Ctrl-A may usually be generated in your editor by
        pressing Alt-1 (the 1 on the keypad). These colors may be imbedded in
        variables or literals. (@=Ctrl-A for the example).
        Variable CmdLine,75,"@112F@007ile @112T@oo7ext..."
        WriteAt  5,3,"@112F@007ile @112T@007ext..."

        Fixed bug in stdout redirection. Previously only > nul was correct.
