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.
