I'm reluctant to admit this, but I'm still unclear about SIIS issues. Could someone please explain what happens to the D- and I-cache in these situations?
Example 1: TxtTRNull TR 0(*-*,R14),NoNulls EX R5,*-6 Example 2: PgmConst LOCTR , TxtTRNull TR 0(*-*,R14),NoNulls PgmCode LOCTR , EX R5,TxtTRNull Example 3: GENCB BLK=ACB,AM=VSAM,MACRF=(KEY,DIR,SEQ,IN), LOC=ANY,RMODE31=ALL, MF=(G,(R5),GENCBLN) +GENCBLN EQU 56 LENGTH OF PARM LIST AREA USED + CNOP 0,4 + BAL 15,*+44 BRANCH OVER CONSTANTS + DC AL1(160) BLOCK TYPE CODE + DC AL1(1) FUNCTION TYPE CODE (16 "DC" lines removed) + DC AL2(0) RESERVED @ + DC B'10000000000000000000000000000000' + LR 1,R5 POINT TO PARAMETER LIST AREA + MVC 16(40,1),0(15) MOVE ACES TO AREA (Please forgive the formatting - it's tough to line things up in a proportional font.) Thanks, Wendell
