Hi
It would appear that open does complete the DCBBLKSI field, or it does on
z/OS 1.13 when the following code is executed.
LA R10,TESTFILE MAKE DCB
USING IHADCB,R10 ADDRESSABLE
OPEN (CAPLIST,OUTPUT,TESTFILE,INPUT)
LH R15,DCBBLKSI
CVD R15,DWORD
UNPK PBLKSI,DWORD+5(3) PRINT
OI PBLKSI+4,X'F0' BLKSIZE
PUT CAPLIST,CAPLINE
CLOSE (CAPLIST,,TESTFILE) CLOSE BOTH FILES.
Kind Regards - Terry
