command #1. W is moved into the program counter in command #2. W+1 is added to the program
counter in command #3. Bit 9 of the program counter is cleared in command #2 and #3, so the jump
destination will be in the first 256 words of any 512-word page. This instruction is useful for jumping
into lookup tables comprised of RETW instructions, or jumping to particular routines. The flags are set
as in an ADD instruction for command #3. If CARRYX is specified, c affects the result of command #3. Insert
a CLC before command #3 to avoid strange results.
