A number of instructions are interruptible and work that way. Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Grinsell, Don Sent: Friday, January 5, 2018 1:12 PM To: [email protected] Subject: SRST Question Has anybody played with the SRST instruction? I am confused by the examples in the PoP. Why do they branch back to the SRST instruction when the string is found, e.g. BC 1,LOOP1? Shouldn't the branch be to the FOUND label, e.g. BC 1,FOUND? L 5,STRAADR L 4,STRALEN AR 4,5 LA 0,X'C1' LOOP1 SRST 4,5 BC 1,LOOP1 BC 2,NOTFND FOUND [Any instruction] ...
