USER INFORMATION FOR ASET-B PROGRAMS

        This disk contains a number of files pertaining to the computer
        program, ASET-B, developed by the Center for Fire Research at the
        National Bureau of Standards. A brief description of the program
        is provided below.

        ASET-B is a program for calculating the temperature and position of
        the hot smoke layer in a single room with closed doors and windows. 
        ASET-B is a compact easy to run program which solves the same
        equations as ASET. The required program inputs are a heat loss
        fraction, the height of the fire, the room ceiling height, the room
        floor area, the maximum time for the simulation, and the rate of
        heat release of the fire. The program outputs are the temperature
        and thickness of the hot smoke layer as a function of time. ASET-B
        was written in BASIC by W.D. Walton. 

ASET-B FILES

        The following files pertain to the ASET-B program.

        ASETB.BAS  The standard version of the ASET-B program.
        ASETB.EXE  The compiled form of the standard ASET-B program. 
        ASETBG.BAS  A modified form of the ASET-B program using large
                    display characters and graphics.
        ASETBPG.BAS  A modified form of the ASET-B program using a pictorial
                     display and graphics.
        ASETBPG.EXE  The compiled form of ASETBPG.
        ASETB.DOC  The complete report and program documentation on the  
                   ASET-B program.

ASETB.BAS

        This is the standard version of the ASET-B program and is run from
        BASIC or BASICA.  This program is a contribution of the National
        Bureau of Standards and is not subject to copyright.  A hardcopy of
        the program's output can be made by typing Ctrl PrtSc after entering
        BASIC but before running the program.

ASETB.EXE

        This is a compiled version of the ASET-B program and is run by
        typing ASETB (with the appropriate disk drive letter if necessary)
        after a system prompt.  It is NOT run from BASIC.  This program is
        identical to the standard version and will run several times
        faster.  It cannot be modified directly.  This file was generated
        with a Microsoft BASIC compiler and portions are copyright Microsoft
        Corp.  This program will use the math coprocessor if it is present.

ASETBG.BAS

        This is a modified form of the standard program and must be run from
        BASICA. It requires a color monitor or monochrome color emulator. 
        It performs the same calculations as the standard program but uses
        large characters for output. In addition, it can produce a graph of
        the results.  This graph is produced by responding to the question
        PLOT RESULTS (Y/N)? with a Y. The graph will appear on the screen
        and the program will pause. At that point, the graph can be copied
        to a graphics printer with a shift PrtSc. Typing any key will cause
        the program to continue. Most computers will require the command
        GRAPHICS to be entered to an operating system prompt before entering
        BASICA in order to copy the graph. Some computers may also require
        a MODE CO40 command to set the proper mode before entering BASICA.

ASETBPG.BAS

        This is a modified form of the standard program and must be run from
        BASICA. It requires a color monitor or monochrome color emulator. 
        It performs the same calculations as the standard program but uses
        large characters for output. Instead of the standard tabular output
        it produces a pictorial representation of a room with a figure
        scaled to the room height. When the run is complete the phrase run
        complete will appear. Strike any key to continue. Like ASETBG this
        program can produce a graph of the results. This graph is produced
        by responding to the question PLOT RESULTS (Y/N)? with a Y. The
        graph will appear on the screen and the program will pause. At that
        point, the graph can be copied to a graphics printer with a shift
        PrtSc. Typing any key will cause the program to continue. Most
        computers will require the command GRAPHICS to be entered to an
        operating system prompt before entering BASICA in order to copy the
        graph. Some computers may also require a MODE CO40 command to set
        the proper mode before entering BASICA.

ASETBPG.EXE

        This is a compiled version of the ASETBPG program and is run by
        typing ASETBPG (with the appropriate disk drive letter if necessary)
        after a system prompt. It is NOT run from BASIC. This program is
        identical to the BASIC version and will run several times faster. 
        It cannot be modified directly. This file was generated with a
        Microsoft BASIC compiler and portions are copyright Microsoft Corp. 
        This program will use the math coprocessor if it is present.

ASETB.DOC

        This file contains a copy of NBSIR 85-3144-1 which is the
        documentation for the ASET-B program.  A hardcopy of this document
        may be obtained by typing PRINT ASETB.DOC.
