MFPR

 The MFPR function returns an unsigned value that is the value of
 a VAX internal processor register.


 Syntax:

    MFPR( ipr_register_expression )


 The  'ipr_register_expression'  parameter   is   an   expression
 compatible with the UNSIGNED type.

 The HP Pascal compiler generates user-mode code.  HP Pascal does
 not  explicitly support the running of VSI Pascal generated code
 in kernel mode.  However, if the following rules  are  observed,
 then the generated code has a good chance of working as expected
 in elevated access modes:

  o  All code must be compiled with  the  /NOCHECK  qualifier  or
     [CHECK(NONE)]  attribute.   The  HP  Pascal  on  OpenVMS VAX
     run-time signaling method relies on trying  to  execute  the
     HALT  instruction.   In  user-mode, this causes an exception
     that is a signal to the  HP  Pascal  run-time  library.   In
     kernel-mode  on an OpenVMS VAX system, this simply HALTs the
     machine.

  o  Avoid  all  routine  calls  which  translate  into  Run-Time
     Library  calls.   These  include  all  I/O routines, several
     arithmetic routines, several string routines, etc.
