                                  MAIN MENU                HEP0.HLP

    The Main Menu  allows you to select the routine or function you want to
    use.  The selection is made by pressing the function key indicated.  At
    the bottom of  the screen you will find  a list of options  that can be
    selected by pressing and holding the  "Alt" key down while pressing the
    letter for the option.

    Alt+H=Help   Alt+P=Print ON/OFF   Alt+F=Function List   Alt+V=Variables

    Each time you press "Alt+P" the print option latches on or off.  In the
    upper left corner you will find the current status of the print option.

    The "Alt+F" will  display the arithmetic functions  available and their
    proper form.

    To see a list of the variable names established, use "Alt+V".

    The input values  may be numbers, variables or expressions  and you may
    use the cursor direction keys, "Ins" and "Del" to edit your input data.
    (See help screens to Calculator.)

    Function key 1 will  put you in the Calculator mode.   In this mode you
    can do many  arithmetic operations from simple  add, subtract, multiply
    and divide to check book balancing to solving formulas.  You can assign
    variable names,  include arithmetic functions  and create a  formula to
    store and  execute.   The input statements  are similar to  Fortran and
    BASIC program statements.

    Function key  2 puts  you into  the Triangle  solving mode.   This will
    solve triangle  problems with a minimum  input and it  assigns variable
    names to  the results  so you can  chain triangle  problems or  use the
    variables in the calculator mode or as input to other routines.

    Function key 3 points to the Circle solving routines.  You can find the
    center and radius for a circle that  passes through three points or you
    can find  the center  of a  circle that  is tangent  to other  circles,
    points or lines.  It also computes  the unknown values for segments and
    sectors.

    Function key 4 will put you in the  Point routine.  Here you can find a
    point that is a given distance and at a given angle from a given point.
    It will also  find the point at  the intersection of two  defined lines
    and find the points of intersection of a circle and a line.

    Function key 5 points  to the Area program.  With this  program you can
    enter a  series of points  as though  connected by straight  lines that
    inclose an area.  The area is then calculated.

    Function key 6 is for the Statistics routines.  You will enter a series
    of values  or a  series of  points.  The  program calculates  the mean,
    standard deviation and  variance.  If the input is points  then it also
    calculates the slope and Y-intercept.

    Function  key 7  will put  you in  the Polynomial  Fit routine.   After
    entering a series of points it  will produce a polynomial equation that
    best fits the points.

    Function key 8 points  to the Beam program.  There are  five classes of
    beams with three different load types.   The program computes the loads
    at the supports, stresses and deflections anywhere on the beam.

    Function key  9 is for the  Helical Spring routines.  The  program will
    compute  the  dimensions and  stresses  in  round wire  compression  or
    extension springs.

    Function key 10  puts you into the Conversion program.   You can select
    the units  to be converted  and then enter  the value to  be converted.
    The program will output the value of the conversion.
