Branch and Hang
BRH

   <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).

   Compare {HCF}.
