Joao, from what I see it appears that the assembler thinks you have an active USING with R13 pointing to the location where the S-con of D000 appears, offset 2AA4 in the listing.
I see you do have an ASMA303W indicating overlapping USING ranges. You do have the active USINGS in the page header, so an additional EJECT just before the PATCH_AREA might help you to pinpoint the problem. Kind regards, Abe Kornelis ========== Op 03/04/2022 om 21:02 schreef João Reginato: > Hi guys > Take a look in these pieces of code compiled in z/OS V2R4: (use any > proportional font like courier for better understanding) > > 000BCC D2A5 D100 8B94 00100 02B94 2107 MVC > WKINFO(LINFO/2),LKINFO INITIALIZE DYNALLOC > 000BD2 D2A5 D1A6 8C3A 001A6 02C3A 2108 MVC > WKINFO+(LINFO/2)(LINFO/2),LKINFO+(LINFO/2) > D 100 02B94 00100 2109 USING LKINFO,WKINFO > ** ASMA303W Multiple address resolutions may result from this USING and the > USING on statement number 781 > 000BD8 4100 D104 02B98 2110 LA R0,LKINFO+4 > RB POINTER > 000BDC 5000 D100 02B94 2111 ST R0,LKINFO > SAVE IT > 000BE0 9680 D100 02B94 2112 OI LKINFO,X'80' > LAST RB > 000BE4 4100 D118 02BAC 2113 LA R0,LKTXTIFC > 1ST TEXT UNIT > 000BE8 5000 D10C 02BA0 2114 ST R0,LKATXTU > SAVE IT > 000BEC 4100 D128 02BBC 2115 LA R0,LKDDNP > USE THIS DDNAME > 000BF0 5000 D118 02BAC 2116 ST R0,LKTXTIFC > SAVE IT > 000BF4 4100 D13A 02BCE 2117 LA R0,LKDSGP > RETURN DSORG > 000BF8 5000 D11C 02BB0 2118 ST R0,LKTXTIFC+4 > SAVE IT > 000BFC 4100 D146 02BDA 2119 LA R0,LKDSNP > RETURN DSNAME > 000C00 5000 D120 02BB4 2120 ST R0,LKTXTIFC+8 > SAVE IT > 000C04 9680 D120 02BB4 2121 OI LKTXTIFC+8,X'80' > LAST TEXT UNIT > ... > 000C20 4110 D100 02B94 2129 S3DYNIOK LA R1,LKINFO > POINTS TO PARAMETERS > 2130 DYNALLOC , > RETURN DSORG & TRUE DSNAME > 2131+* MACDATE Y-2 73082 > 000C24 0A63 2132+ SVC 99 CALL DYNAMIC > ALLOCATION > ... > Up to here everything appears to be ok.
