 The keys in this menu perform operations on binary integers.  Note that
 both logical and arithmetic right-shifts are provided.  <INV LSH>
 rotates one bit to the left.
 
    The “difference” function (normally on ‘b d’) is on <INV AND>.  The
 “clip” function (normally on ‘b c’) is on <INV NOT>.
 
    The <DEC>, <HEX>, <OCT>, and <BIN> keys select the current radix for
 display and entry of numbers: Decimal, hexadecimal, octal, or binary.
 The six letter keys <A> through <F> are used for entering hexadecimal
 numbers.
 
    The <WSIZ> key displays the current word size for binary operations
 and allows you to enter a new word size.  You can respond to the prompt
 using either the keyboard or the digits and <ENTER> from the keypad.
 The initial word size is 32 bits.
