! DECnet message processing macros
!
!	N.B - These macros are here for convenience at this time only
!             and are specific to BLISS-36. 
!
!             THEY ARE NOT TRANSPORTABLE! In time they will have to

%sbttl 'Write Macros'

! Macro - PUTB
!
! Function - To write a 8 bit value to the next position in
!            a DECnet byte string.  The pointer to the byte
!            string is updated to point to the next free position.
!
! Parameters -
!
!    VALUE      8 Bit value to write
!    POINTER    Address of byte string pointer


macro
     PUTB (VALUE, POINTER) =
         ch$wchar_a (VALUE, POINTER) %;


! Macro - PUTW
!
! Function - To write a 16 bit value as the next two bytes in
!            a DECnet byte string.  The pointer to the byte
!            string is updated to point to the next free position.

! Macro - %SUBI32
!
! Function - This macro subtracts a fullword value from a
