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.
