Issue/Introduction

Does CONTROL access imply READ for the ZMFAPLA resource class?

Resolution

No. Listing the ZMFAPLA resource class in the RDT displays the following:

TSS LIST(RDT) RESCLASS(ZMFAPLA)

ACCESSORID = *RDT*     NAME       = RESOURCE DEFINITIONS                
                                                                        
  RESOURCE CLASS = ZMFAPLA                                              
   RESOURCE CODE = X'157'   POSIT =    592                              
       ATTRIBUTE = MASKABLE,MAXOWN(26),MAXPERMIT(246),ACCESS,PRIVPGM,MIX
          ACCESS = NONE(0000),ALTER(1C00),CONTROL(0400),UPDATE(6000)    
          ACCESS = READ(4000),ALL(FFFF)                                 
          DEFACC = READ                                                 

The binary values for the bits for CONTROL access do not map into the binary values for the bits for READ access.

(x'0400' = binary 0000 0100 0000 0000) CONTROL

(x'4000' = binary 0100 0000 0000 0000) READ

This means CONTROL access does not include READ access for this resource class.
