The $CHGMAN resource class is defined in the Top Secret RDT (Resource Descriptor Table) as follows:
RESOURCE CLASS = $CHGMAN RESOURCE CODE = X'13F' ATTRIBUTE = MASKABLE,MAXOWN(26),MAXPERMIT(044),ACCESS,PRIVPGM ACCESS = READ(4000),NONE(0000),UPDATE(8000),WRITE(2000),ALL(FFFF) DEFACC = READ
Note the hexadecimal value of accesses READ and UPDATE, respectively, 4000 and 8000.
How do you define the access levels so that UPDATE access implies READ ?
Change UPDATE=8000 in the ACLST to UPDATE=6000 for the $CHGMAN resource class and put the access levels in hexadecimal descending order.
TSS REPLACE(RDT) RESCLASS($CHGMAN) ACLST(ALL=FFFF,UPDATE=6000,READ=4000,WRITE=2000,NONE=0000)
Then UPDATE access will allow READ access.
