VERR              Verify Read (286/386)              Flags: O D I T S Z A P C
                                                                      *
VERR source

           Logic:        if source can be read from then ZF . 1
                         else ZF . 0

     This instruction sets the zero flag if the current procedure can use
     source as a selector to read from. If the zero flag is not set,
     reading from source will cause a memory fault.
