UNIVERSAL PUPSYM - SYMBOLS FOR PUP ETHERNET
SEARCH MACSYM
EXTERN PBHEAD

COMMENT	\

    These are the symbols used by the Stanford MEIS based implementation
of TOPS-20 PUP Ethernet.  They are used by any program that needs to manipulate
actual pup packets.

    This file is similar to, but different from, the SU PUPPAR universal
library.  Make sure you use the correct library.

;PUP Packet buffer definitions

COMMENT \

These are the packet header field definitions that go with the 32-bit
header mode.  Make sure you want to use this file instead of PUPPAR.

The user should define the symbol PBHEAD to be the offset off of PB of
the first PUP packet word (usually zero).
