(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).
