  Menu navigation can be performed with the keyboard or with
  a ^mouse^ if you have one installed.  You may move horizon-
  tally from one menu selection to another with the arrow
  keys or if you prefer you can click on the selection with
  your left mouse button.  To access the pull down menu
  simply tap <ENTER> or the down arrow key.  Arrow keys will
  move you around the menu selections.  To select a high-
  lighted menu item tap <ENTER> again.  <ESC>ape will back
  you out of nearly any place in the program.

*B 2,Triangles

                           TRIANGLES

  Solve unknown sides/angles of a partially known triangle.
  Two types are represented: RIGHT and OBLIQUE.  If you know
  that your triangle has a 90 degree angle in it you should
  use the RIGHT triangle selection.  If you are unsure That
  a 90 degree angle exists then use the OBLIQUE selection.

*B 3,Right Triangles

                        RIGHT TRIANGLES

  A right triangle is a triangle that contains one 90 degree
  angle in it.  If you are certian that the triangle you
  want to solve does have a 90 degree angle in it then this
  is the proper menu selection to use.  If you are unsure of
  this fact then you should use ^OBLIQUE TRIANGLES^ to solve
  the problem.

*B 4,Oblique Triangles

                       OBLIQUE TRIANGLES

  An oblique triangle can be of any shape as long as it does
  not contain a 90 degree angle.  If it does contain a 90
  degree angle it is considered a "right triangle" and
  should be calculated as such.  You will have to supply
  three items of information about your triangle in order to
  solve it.  This information MUST contain the length of one
  side plus:

                2 sides,
           or   1 side and 1 angle,
           or   2 angles.

*P


  It is preferable to enter as many sides as possible be-
  cause doing so will tend to slightly enhance accuracy.

*B 5,Polar

                      POLAR CALCULATIONS

  Solve unknown angles/vectors/coordinates between two
  points located on a cartesian coordinate grid.  Two ways
  of accomplishing this are provided:

             ^Point-Distance-angle^, and
             ^Two Known Points^






  Also see:  ^Menu^  ^Cartesian coordinates^
*E

  --------------------------------------------------------------

*B 6,Point-Distance-Angle

                   POINT-DISTANCE-ANGLE

  Use POINT-DISTANCE-ANGLE to determine X & Y coordinates of
  a point located on a ^Cartesian coordinates^ grid.  You
  will be asked to supply four items of information:

   POINT 1 X&Y:
              The "base" location from which POINT 2 will
              be calculated.  These may be positive or
              negative values.

    DISTANCE: The distance from POINT 1 to POINT 2.  This
              should be a positive value.
*P
       ANGLE: The angular direction (vector) from the base
              point to the unknown point.  This may be a
              positive or negative value.  0 degrees and 360
              degrees would describe a line heading from
              left to right.  90 degrees would describe a
              line heading upward.

              You may also want to use the ^DMS calculator^
              (F5) or the ^Radians->Decimal Calculator^ (F6)
              to convert an angle.

  After you have entered the above information Point-Dis-
  tance-Angle will supply you with the X-Y coordinates of
  the unknown point.

*B 8,File

                             FILE

  At nearly any point in ANGLES you have the ability to load
  a triangle solution that was previously saved.  The loaded
  or recalled solution may then be printed or just visually
  referenced.  If a solution will no longer be needed you
  also have the option to delete it with ^Delete File^.

*B 9,Load File

                           LOAD FILE

  Load allows you to recall a solution that you have previ-
  ously saved to disk for viewing.  If you would like to
  print the the solution you may do so by tapping F10.  Load
  file is available at any point in ANGLES by simply tapping
  the F3 "hot" key.  After you press F3 you will be shown a
  directory listing of all the ANGLES solution files that
  were saved in the current directory.  To select a directo-
  ry or a file just highlight the selection you want and tap
  <RETURN> or click on it with the left mouse button.  If no
  previously saved ANGLES files exist in the current direc-
  tory you will be notified.

*B 12,Fix

                              FIX

  OPTIONS: FIX will set the decimal precision with which
  ANGLES displays its solutions.  Only 3 through 9 decimal
  places are allowed.  Numbers that must be rounded will be
  rounded to the next highest values.

         For instance:  FIX |    PI
                       -------------------
                         3  | 3.142
                         4  | 3.1416
                         5  | 3.14159
                         6  | 3.141593
                         7  | 3.1415927
*P

                        FIX |    PI
                       -------------------
                         8  | 3.14159265
                         9  | 3.141592654

  Fix does not affect internal calculation precision, only
  the precision with which solutions are displayed.

  When you choose Fix you must enter the desired number (3
  through 9) and press <ENTER>.  You will then be asked if
  you would like to save the new number as the default.  If
  you answer "yes" ANGLES will use the decimal precision you
  specified as its default value.  If you answer "no" the
  new number will only be used for this session and will not
  be saved.

*B 13,DMS Calculator

             DEGREES, MINUTES, SECONDS CALCULATOR

  Sometimes you may run across an instance that you only
  know an angle in a "degrees, minutes, seconds" format.
  The ANGLES program will only accept an angle in a decimal
  degrees format.  The degrees, minutes, seconds calculator
  (DMS for short) is provided to automatically calculate the
  decimal degrees equivelant of your angle.

  If you choose the DMS calculator from the main menu Simply
  type in the appropriate information and the answer will be
  displayed.  If, however you are entering data to solve a
  problem you may press the F5 "hot" key and the DMS calcu-
  lator will "popup".  After you enter the degrees, minutes,
  and seconds the answer will be displayed and you will be
*P
  asked if you want to export it.  If you type a "Y", or hit
  <ENTER> the converted decimal angle will be typed in the
  input field for you.  If you type a "N" the calculator
  will disappear and you can pick up where you left off.

*B 16,Triangle View Selection

                    TRIANGLE VIEW SELECTION

  Wether you are about to solve a right triangle or an
  oblique triangle you now have 8 different views to choose
  from.  These different views are intended to be an aid in
  helping you visualize the triangle you must solve.

  Select a view by one of three ways:

      1) If you have a mouse installed simply move the
         mouse up or down and the views will scroll by.
         When you find a suitable view tap your left mouse
         button and ANGLES will prompt you for the triangles
         known information.
*P

      2) The number keys 1 through 8 across the top of your
         keyboard will select the coresponding view number.
         Tap <ENTER> to input the triangles known informa-
         tion.

      3) Use the arrow keys (up, down, right, left) to move
         through the views.  PageUp and PageDown also move
         you up or down through the views.  Tap <ENTER> to
         input the triangles known information.
*E

  --------------------------------------------------------------

*B 17,Side input

                          SIDE INPUT

  You must supply ANGLES with at least one side dimension
  for your triangle.  If you have a choice to enter one side
  or one angle the side would be preferable.  If you don't
  know how long a side is simply tap <ENTER>.  A question
  mark will appear to indicate that the side is unknown and
  you will pass to the next position.  A zero (0) entry is
  counted as an unknown side.  If you accidentally pass up
  an entry field just tap your up arrow key to go back.
  ANGLES accepts mathematical expressions also:

                  +   plus
                  -   minus
                  *   multiply
*P

                  /   divide
                 ()   prenthases

  Example entries:

       4.1 + (.625/2) <ENTER>    will yield 4.41250000
       5.25 / 2 * 8   <ENTER>    will yield 21.0000000
       5.25 / (2 * 8) <ENTER>    will yield 0.32812500
       5+5            <ENTER>    will yield 10.0000000

  Spaces may be included in your entry if you like but they
  are not neccesary.  If you have entered something that
  ANGLES does not recognize as a valid expression an error
  window will popup to inform you of the problem.  After you
  read the message, tap a key and the cursor will be blinking
*P

  under the unrecognized character.  Don't forget to make
  sure your prenthases match up!
                      ------------------

                         INPUT STATUS

  As you move around on the data entry form entering the
  known information, you will notice the lower center sec-
  tion of the screen contains input status infomation.  This
  information changes to inform you of what ANGLES needs, or
  doesn't need.  When ANGLES is satisfied with your input it
  will read "SUCCESS".  Remember that if ^Auto Calc^ is on,
  your triangle will be solved immediatly upon SUCCESS.

*B 18,Angle Input

                          ANGLE INPUT

  For an unknown angle simply tap <ENTER>.  A question mark
  will appear to indicate that the angle is unknown and you
  will pass to the next field.  A zero (0) entry is counted
  as an unknown angle.  If you accidentally pass up an entry
  field just tap the up arrow key to go back.

  ANGLES expects angular data to be entered in a decimal
  degrees format.  If you know an angle but it is called
  out in a degrees, minutes, seconds format simply tap F5
  to call up the ^DMS calculator^.  If you know the angle in
  radians you can convert it to decimal by tapping the F6
  key and inputting the radians.

  ANGLES also accepts mathematical expressions:

                  +   plus
                  -   minus
                  *   multiply
                  /   divide
                 ()   prenthases

  Example entries:

       85-12.5        <ENTER>    will yield 72.5000000
       5.25 / 2       <ENTER>    will yield  2.6250000
       5.25 / (2 * 8) <ENTER>    will yield  0.3281250
       15+15          <ENTER>    will yield 30.0000000

*B 19,Two Solutions

                         TWO SOLUTIONS

  There are two possible solutions to the triangle you have
  just defined.  The angle shown in the dialogue box could
  be either greater or less than 90 degrees and still fit
  the information you have supplied.  If you choose greater
  than 90 degrees ANGLES will solve your triangle according-
  ly.  Likewise if you choose less than 90 degrees ANGLES
  will solve for that possiblity.

  You may view the other solution by toggling ^Auto Calc^
  back on and re-calculating the triangle.
*E

  --------------------------------------------------------------

*B 20,Continue

                           CONTINUE

  Continue will take you back to the side and angle data
  entry fields so you may edit some of the the triangle's
  known information.  The values you have already entered
  will be preserved but you may delete or modify them.  If
  you would like to clear all the fields you can type a "C".

  Please take note that once a solution has been displayed
  ^Auto Calc^ will be toggled off and must be manually
  turned on to solve for new input.

       15+15          <ENTER>    will yield 30.0000000

  Spaces may be included in your entry if you like but they
  are not necessary.  If you have entered something that
  ANGLES does not recognize as a valid expression an error
  window will popup to inform you of the problem.  You will
  then be returned to the input field with the cursor locat-
  ed under the unrecognized character.

*B 28,Mouse

                         MOUSE SUPPORT

  If you have a mouse installed on your system ANGLES will
  support it.  The left button will act the same as if you
  pressed the <ENTER> key.  The right button acts the same
  as if you typed ESCape.  If you have a middle button it
  will function the same as the right button.

  To select from a menu bar simply place the mouse cursor on
  the item you want and tap the left button.  To back out of
  many places in ANGLES simply tap the right button one or
  more times.  In some instances the right button will not
  work, but the ESCape key will always backup one step

*B 29,Help on Help

                         HELP ON HELP

  ANGLES context sensitive help system is provided to give
  you specific information about any field that the cursor
  may be resting upon.  It also features cross referencing
  to other help catagories to assist you in understanding
  the topic at hand.  ANGLES help will be a real asset to
  those who (like myself) don't like to read all the docu-
  mentation before they dig in to a program.  To use the
  online help system simply highlight the selection you want
  information about and tap F1.  The cross referenced sub-
  jects will stand out from the normal text.  You may access
  the subjects by pressing the <ENTER> key.  If there are
  more than one subject in the window you can move amoung
  them with the arrow keys.  ESCape to quit.

*B 30,Registration

                        PLEASE REGISTER

  If you decide to use ANGLES please register your copy.
  ANGLES is not intended to be "freeware" but is user sup-
  ported software, or Shareware.  For your convenience I
  have provided a registration form for you to fill out and
  send in.  This form is found off the main menu under
  "Options" - "Register".

  Any comments/suggestions would also be appreciated!




  Thank you!

*B 31,Auto Calc

                     AUTOMATIC CALCULATION

  Automatic Calculation, or "AutoCalc" is basically an
  ON/OFF toggle switch.  The current AutoCalc status is
  shown in the right center window of the screen.  To toggle
  AutoCalc simply tap the "A" key.  You will hear a low
  frequency "blip" when you toggle AutoCalc OFF and a higher
  frequency "blip" when toggled ON.

  When AutoCalc is toggled ON it allows ANGLES to solve your
  triangle the instant enough information has been input.
  If it is toggled OFF it will not allow ANGLES to solve a
  triangle.  The purpose of the OFF mode is to allow you to
  change your triangles sides and/or angles without con-
  stantly being given a solution.
*P

  When you first begin angles data input AutoCalc will be
  ON.  As soon as you have entered enough information to
  solve the triangle you will be whisked to the solution
  screen.  After you return from the solution screen Auto-
  Calc will be toggled OFF.  When AutoCalc is OFF you may
  change any information but your triangle will not be
  solved until AutoCalc is toggled back ON by tapping the
  "A" key.

*B 32,Cartesian coordinates

                     CARTESIAN COORDINATES

  The polar menu selections in ANGLES are based on a system
  of coordinates sometimes referred to as the cartesian
  coordinate system.  Cartesian coordinates are laid out in
  a grid like this:
                            (+Y)
                              |
                              |
                   (-X) ------+------ (+X)
                              |
                              |
                            (-Y)

  The Y axis is defined by the vertical line and the X axis
*P
  is defined by the horizontal line.

  A point may be defined on this coordinate system by speci-
  fying it's X&Y values (the X axis is always defined first,
  then the Y axis).  For instance (5,2) would locate a point
  5 units to the right of the Y axis at X=5, and 2 units
  above the X axis at Y=2.

  Negative values may also be specified for example (-2.5,0)
  would locate a point 2-1/2 units to the left of the Y axis
  at X=-2.5, and zero units from the X axis (directly on the
  X axis line) at Y=0.

  Angular directions in ANGLES coordinate system should
  always be called out in decimal values not degrees,
  minutes, seconds, or radians.
*P

  Anglular directions are treated as shown:

                           (-270)
                            (+90)
                              |
                 (-180)       |       (360)
                 (+180) ------+------ (0)
                              |
                              |
                           (+270)
                            (-90)

  As you can see the angle is always determined FROM the
  point of origin (0,0).

*B 36,Decimal->DMS Calculator

    DECIMAL DEGREES to DEGREES, MINUTES, SECONDS CALCULATOR

  This option is provided for those who need to convert a
  decimal degree angle to its degrees, minutes, seconds
  equivalent.  Enter the decimal degrees, press <ENTER> and
  the answer will be displayed.

*B 37,Radians->Decimal Calculator

             RADIANS to DECIMAL DEGREES CALCULATOR

  Sometimes you may run across an instance that you only
  know an angle in radians.  ANGLES will only accept an
  angle in a decimal degrees format.  The Radian calculator
  is provided to automatically calculate the decimal degrees
  equivelant of your angle in radians.

  If you choose the Radian calculator from the main menu
  Simply type in the appropriate information and the answer
  will be displayed.  If, however you are entering data to
  solve a problem you may press the F6 "hot" key and the
  Radian calculator will "popup".
*P

  As soon as you enter the angle in radians the answer will
  be displayed and you will be asked if you want to import
  it.  If you type a "Y", or hit ENTER the converted decimal
  angle will be typed in the input field for you.  If you
  type a "N" the calculator will disappear and you can pick
  up where you left off.

*B 42,Conversions

                          CONVERSIONS

  ANGLES will only accept angular data in a decimal degrees
  format.  Frequently you may have the need to convert to
  decimal degrees from some other angular format such as
  radians or degrees, minutes, seconds.  You may also need
  to convert your answers back into the original format.
  All these thing may be accomplished using the four calcu-
  lators supplied:

   1) Degrees, minutes, seconds  convert to Decimal degrees
   2) Radians convert to Decimal degrees
   3) Decimal degrees convert to Degrees, minutes, seconds
   4) Decimal degrees convert to Radians
*P

  The first two calculators may be "hot" keyed from anyplace
  in ANGLES to do your conversions into decimal format.  The
  hot key for the degrees, minutes, seconds to decimal
  calculator is F5.  The hot key for the radians to decimal
  degrees is F6.
