The ICM will only replace the lower 3 bytes of R1. If there is anything in the left most byte it will not be replaced. You could try
SR R1,R1 ICM R1,7,0(R2) And see if that gets you what you want. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Crabtree, Anne D Sent: Thursday, August 04, 2011 8:02 AM To: IBM-MAIN@bama.ua.edu Subject: assembler help! In our IEFACTRT (accounting exit), an assembler program, it has the following commands: L R2,PARMJOBC ICM R1,7,0(R2) If PARMJOBC contains a binary integer length of 4 with 00 00 00 08, what ends up in all bits of R1? I am trying to add additional values to what is in R1 by doing: MVC WK1(4),SMF30CPS A R1,WK1 This is not doing what I want it to do! If SMF30CPS, also a binary integer length of 4, has 00 00 00 01, what ends up in R1? Anne D.
