any access registers? ________________________________________ From: IBM Mainframe Assembler List [[email protected]] on behalf of [email protected] [[email protected]] Sent: Sunday, August 17, 2014 4:24 PM To: [email protected] Subject: Can Someone Point Out My error Here Im executing 5 Instructions and then I force an Abend. I load the address of a storage area into Register 1 nd verify it by the presence of an eye-catcher. After executing the 5 instructions below; I expect the area Labeled "LOCLCOMM" to contain a copy of the eye-catcher that Register 1 is pointing to. However after execiting the 5 instructions the area LOCLCOMM contains 256 Binary zeroes ??? . . There is No Multi Tasking as this is a single TCB program. . .
