NAME
       dxcalc - DECwindows interface to the calculator

SYNOPSIS
       dxcalc [flags]

FLAGS
       Specifies  the color of the window's border (color displays only).  The
       default is specified by means of the Session Manager's  Customize  Win‐
       dows dialog box.	 Specifies the color of the window's background (color
       displays only).	The default is specified by means of the Session  Man‐
       ager's  Customize  Windows dialog box.  Specifies the display screen on
       which dxcalc displays its window.  If the display option is not	speci‐
       fied, dxcalc uses the display screen specified by your DISPLAY environ‐
       ment variable.  The display  option  has	 the  format  hostname:number.
       Using two colons (::) instead of one colon (:) indicates that DECnet is
       to be used for transport.  The default is :0.   For  more  information,
       see  X(1X).   This  option is the same as the -d option.	 Specifies the
       color of the text (color displays only). The default  is	 specified  by
       means  of the Session Manager's Customize Window dialog box.  Specifies
       the font for calculator menus.  (Key fonts are automatically scaled  to
       match the size of the calculator.)  The default font is menu12.	A font
       value specified in the .Xdefaults file overrides this  option.	Speci‐
       fies  the  width,  length,  and	location of the dxcalc window.	If the
       geometry option is not specified,  dxcalc  uses	default	 values.   The
       geometry	 option	 has  the format [widthxlength][{+-}x{+-}y].  For more
       information about the screen coordinate system, see X(X).

DESCRIPTION
       The dxcalc command displays a 27-function calculator  with  one	memory
       location	 that  is always visible.  The dxcalc calculator has a maximum
       display of 15 digits.

       To press a button displayed in the dxcalc window, click on it with  MB1
       (the  left  mouse  button, unless you have redefined it).  In addition,
       you can enter numbers by typing them in from the keyboard.  To  perform
       a  function  from  the  keyboard,  check	 the key binding listed in the
       application's on-line help or in this reference page.

   File Menu
       The File menu contains the following items: Saves the calculator's size
       and position, to use the next time you run  the	calculator.   Restores
       the use of the system default values for size and position.  Closes the
       dxcalc window.

   Edit Menu
       The Edit menu contains the following items: Undoes the  last  keystroke
       or  operation.  Copies the selected text onto the clipboard.  Pastes in
       text from the clipboard.

       the  dxcalc  window  and	 click	MB3.  This menu contains the following
       items: Undo Copy Paste Exit

   Key Bindings
       The dxcalc application has a specific set of key	 bindings  that	 allow
       you to use the keypad for all mathematical functions.  The built-in key
       bindings are as follows: The numbers on the keypad and the  numbers  in
       the  number  line  map  to themselves.  Clears both the display and the
       accumulator. Maps to the C key and the F1  key.	 Clears	 the  display.
       Maps to the E key and the F2 key.  Returns the square root of the value
       in the display. Maps to the Q keyboard key and the PF2  numeric	keypad
       key.   Adds  the	 value in the display to the value in the accumulator.
       Maps to the plus symbol (+) in the number line and the comma key (,) in
       the  keypad.   Subtracts the value in the display from the value in the
       accumulator.  Maps to the minus sign (-) in the	number	line  and  the
       minus  sign  in the keypad.  Multiplies the value in the accumulator by
       the value in the display.  Maps to the asterisk (*) and to the PF3 key.
       Divides	the value in the accumulator by the value in the display. Maps
       to the slash (/) key on the keyboard and the PF1	 key  in  the  keypad.
       Changes the value in the display from positive to negative or from neg‐
       ative to positive. Maps to the n key.  Maps to the percent (%) keyboard
       key and the PF4 keypad key.  Clears the contents of memory. Maps to the
       m key/c key sequence and to the F17 key.	 Subtracts the	value  in  the
       display	from the value in memory. Maps to the m key/- key sequence and
       to the F18 key.	Adds the value in the display to the value  in	memory
       and  stores  the result. Maps to the m key/plus (+) key sequence and to
       the F19 keypad key.  Places the contents of the memory in the  display.
       Maps  to	 the  m	 key/r	key sequence and to the F20 key.  Displays the
       result of the last operation (or series of operations).	 Maps  to  the
       Enter, Do, and Return keys.  Inserts a decimal point into the number in
       the display.  Maps to the period	 keys  on  the	keyboard  and  keypad.
       Places  the  value  for	PI in the display. Maps to the p keyboard key.
       Inverts the next operation.  Maps to the i and F3  keys.	  Returns  the
       sine  of	 the  value  in	 the  display.	(If the inverse setting is on,
       returns the arcsine.)  The angle is in degrees, radians, or  gradients,
       according  to  the state of the degrees key. Maps to the s and F4 keys.
       Returns the cosine of the value in the display. (If the inverse setting
       is  on,	returns	 the  arccosine.) The angle is in degrees, radians, or
       gradients, according to the state of the degrees key.  Maps  to	the  o
       and  F5 keys.  Returns the tangent of the value in the display. (If the
       inverse setting is  on,	returns	 the  arctangent.)  The	 angle	is  in
       degrees,	 radians,  or gradients, according to the state of the degrees
       key.  Maps to the t and F6 keys.	 Returns the  log  (base  10)  of  the
       value in the display.  (If the inverse setting is on, returns 10 to x.)
       Maps to the l key/o key sequence and to the F7 key.  Returns the	 natu‐
       ral log of the display. (If the inverse setting is on, returns e to x.)
       Maps to the l key/n key sequence and to the F8 key.  Returns the	 value
       in the accumulator raised to the power of the value in the display. (If
       the inverse setting is on, returns y to the minus x.)  Maps to the cir‐
       cumflex (^) and F10 keys.  Switches the measurement unit for trig func‐
       tions among degrees, radians, and gradients. Maps  to  the  d  and  F11
       keys.  Returns the factorial of the display (n*(n-1)*(n-2)...*1).  Maps
       to the exclamation mark (!) and F12 keys.  Returns  the	reciprocal  of
       the display. Maps to the tilde (~) and F13 keys.	 Returns a random num‐
       ber between 1 and the display. Maps to the r and F14 keys.

   X Defaults
       The dxcalc application uses the values in the .Xdefaults file when  you
       logged  in  and	uses  the appropriate resource specification values to
       customize the appearance of  the	 dxcalc	 window.   The	format	for  a
       resource specification in the .Xdefaults file is:

       [name*]resource:	 value

       Specifies  the  application  name or the name string that restricts the
       resource assignment to that application or to a component of an	appli‐
       cation.	 If this argument is not specified, the resource assignment is
       globally available to all  X  applications.   Specifies	the  resource.
       Specifies  the  value  that is to be assigned to the resource.  Because
       each toolkit-based application can consist of a combination of  widgets
       (for  example,  push  buttons  and a scroll bar), you can form the name
       string by adding widget class and name identifiers to the string.   For
       further information about adding class and name identifiers, see X(1X).

       For dxcalc, the available class identifiers are: Calc MenuBar

       For dxcalc, the available name identifiers are: sqrtFontFamily KeyFont‐
       Family

       The general resources listed in X(1X) apply to dxcalc.

       The fonts used by dxcalc are specified by an  asterisk  (*).   This  is
       done so that a font family is chosen instead of a particular font.  The
       asterisk (*) is a wildcard character that matches all font sizes.
