The change is this:
SYSSTATE ARCHLVL=2 yields:
GETMAIN RU,LV=(0),SP=0,LOC=(24,64) GETMAIN WORKAREA
+ DS 0H @P5C
01-GETM
+IHB0005C DS 0H
01-GETM
+ L 15,=AL1(B'00010000',(0),(0),B'01010010')
X01-GETM
+ LOAD GETMAIN
PARMS
+ SR 1,1 ZERO RESERVED REG 1
01-GETM
+ SVC 120 ISSUE GETMAIN SVC
01-GETM
instead of:
GETMAIN RU,LV=(0),SP=0,LOC=(24,64) GETMAIN WORKAREA
+ CNOP 0,4
01-GETM
+ B IHB0004C BRANCH AROUND DATA
01-GETM
+IHB0004F DC BL1'00010000' Flags. @L7C
01-GETM
+ DC AL1(0) RESERVED
01-GETM
+ DC AL1(0) SUBPOOL
01-GETM
+ DC BL1'01010010' MODE BYTE @G860P30

+IHB0004C DS 0H

+ SR 1,1 ZERO RESERVED REG 1
01-GETM
+ SVC 120 ISSUE GETMAIN SVC
01-GETM
