<humour> (BRH) Originally a mythical instruction for the IBM 1130 at Indiana University.
Later some real examples were discovered. The Texas Instruments TI-980 allowed all addressing modes with all instructions, including Store Immediate Extended (stores the value into the extension word of the instruction) and Branch and Link Immediate (makes a subroutine call to the same instruction -- Branch and Hang).
