	 This file contains all the symbol definitions for the Data
Access protocol (DAP) of DECnet. Any program directly implementling this
protocol should search DAPSYM to get the symbols it needs for processing.
In particular the FAL and NFT implementations for DECnet-20 use this
universal file.

DAP messages consist of a stream of eight-bit bytes as required by NSP.
Each box in the diagrams represents an eight-bit PDP-11 byte, rather than
the standard DECsystem-20 Thirty-six bit word.  It is left to the user's
imagination how to build these messages and pack the bytes into 36 bit
words. Where bit definitions are given, the bits are defined as though
the byte is right-justified in the DECsystem-20 word.

	A DAP Message Takes the following form:

		!=====================================!
		!       TYPE(1) B: Message Type       !
		!-------------------------------------!
		!           FLAGS(EX-5) BM:           !
		!-------------------------------------!
		!      STREAMID(1) B: (Not used)      !
		!-------------------------------------!
		!   LENGTH(1) B: Length of OPERAND    !

		!   LEN256(1) B: MSB of Length        !

		\                                     \

The TYPE values are defined along with their corresponding message

	HD$LEN==1B34		;(bit 1) Length field Present (for blocked DAP msgs)
	HD$LN2==1B33		;(bit 2) Extended length (LEN256) field present
	HD$BCT==1B32		;(bit 3) BITCNT field present
	HD$SEG==1B31		;(bit 4) This not the last message segment


;The STREAMID field should contain the data stream number established by
;doing a CONTROL(Connect), otherwise it should be omitted

;The LENGTH field contains the operand length for blocked messages
		
;The LEN256 contains the MSB of a two-byte OPERAND length field, if required

;The OPERAND field is message-specific and is defined for each message
SUBTTL	Defined DAP argument types

;Each of the following argument types has a specific data format
;and a related processor in DAPLIB for processing the argument.

;Two fields are defined for each argument type

;  1.	The argument type name

;  2.	Number of significant bits per DAP message byte
;	This allows the storage for each argument field to
;	be defined on an as required basis in DAPLIB.

;Define a macro to declare the valid argument types

DEFINE MSGARG <

XX	FIX,^D8	;;Argument is a Byte or Group of bytes
XX	VAR,^D7	;;Argument is variable length ascii field
XX	INT,^D8	;;Argument is variable length integer field
XX	EXF,^D7	;;Argument is an extensible field
XX	MNU,^D7	;;Argument is a menu which specifies what's to come

>

;DAP message argument types are described below.  Each argument type
;Each argument type has an associated processor for getting and putting
;the argument

;MNU	Field is a menu which determines which message fields follow
;	Menu's are stored as extensible fields and cause 1 word of
;	storage to be reserved for every 5 DAP bytes

;EXF	Field is an extensible field which is generally used as a bit
;	map of specific options requested or a menu of message fields
;	which follow.  Extensible fields have 7 information bits per
;	DAP byte and are stored as 36 information bits per word.
;	Bit 35 is the least significant bit of the extensible field.

;FIX	Field is a FIXe or group of FIXes.  Dap FIXes are stored
;	right justified 4 per 36 bit word.

;INT	Field is a variable length unsigned integer.  The DAP field
;	is stored as a 36 bit integer value

;VAR	Field is a variable length Ascii field.  It is stored as an
;	ASCIZ string of 7 bit bytes.


;PRO	Field is a file protection field.  Dap protection codes are
;	translated to system protection mask.

;DAT	Field is an Image field of a DATA message.  This field is not
;	stored, but is processed by the apporpriate data processor

;DTI	Field is an 18 byte DATE/TIME argument specification.  This
;	field is stored internally as a 36 bit quantity
