minus-squareAmberskin@europe.publinkfedilinkarrow-up0·1 year agoJust to boast my old timer credentials. There is an utility program in IBM’s mainframe operating system, z/OS, that has been there since the 60s. It has just one assembly code instruction: a BR 14, which means basically ‘return’. The first version was bugged and IBM had to issue a PTF (patch) to fix it.
