System Macros Invoked by Drivers
CPUDISP
CPUDISP
Causes a branch to a specified address according to the CPU type of the VAX
processor executing the macro code.
Format
CPUDISP addrlist ,[environ=VMS] ,continue=NO
Parameters
addrlist
List containing one or more pairs of arguments in the following format:
<CPU-type, destination>
The CPU-type parameter identifies the type or subtype of a VAX processor for
which the macro is to generate a case table entry. The CPUDISP macro identifies
the VAX system by type as listed in Table 2–2.

Because the VAX–11/785 has the same CPU type as the VAX–11/780, the CPUDISP macro contains
special code to distinguish between the two processors. This code tests a bit within the processor’s
system identification register (PR$_SID) that indicates whether it is a VAX–11/785.
