Interpreting the Contents of Field NMRMSG

To determine the contents of the NMRMSG field at offset X‘1E’, you must also examine the contents of the NMRTYPE4 field at offset X‘02’ and the NMRTYPET field at offset X‘00’. Use Table 1 to determine the contents of NMRMSG.

Table 1. Interpreting Field NMRMSG
NMRTYPE4	NMRTYPET	NMRMSG Contents
0	0	Time stamp and the text of the message which starts at NMRMSG + 8.
0	1	The text of the message, which starts at NMRMSG.
1	0	Time stamp, userid, and the text of the message, which starts at NMRMSG + X‘10’.
1	1	Userid and th etext of the message, which starts at NMRMSG + 8.

Table 2. Fields in the Messages NMR
Field Name	Offset in Hex	Length	Type of Data	Default Value	Valid Range	Description
NMRFLAG	0	1	bits	0	none	Flag byte.
bit NMRFLAGC		.1	80 bit	0	0	0 indicates the NMR contains a message.
bit NMRFLAGW		.1	40 bit	0	none	If on, the NMROUT field contains the remote number. AS/400 sets this bit to 0, but does not use it. RSCS does not use or set the bit.
bit NMRFLAGT		.1	20 bit	0	none	If on, the NMROUT field contains the destination userid. AS/400 always sets and uses this bit. JES3 and POWER do not use the bit.
bit NMRFLAGU		.1	10 bit	0	none	If on, the NMROUT contains the destination console identifier. AS/400 sets this bit to 0, but does not use it. POWER does not use this bit. RSCS does not use the bit.
bit NMRFLAGR		.1	08 bit	0	none	Not used for messages.
bit NMRFLAGJ		.1	04 bit	0	none	Not used for messages.
bit NMRFLAGD		.1	02 bit	0	none	Not used for messages.
bit NMRFLAGS		.1	01 bit	0	none	Not used for messages.
NMRLEVEL	1	.4	bits	0	none	The importance level of the NMR. The bit definitions are: `X'10' Non-essential messages X'30' Normal messages X'50' Messages requiring delayed operator action X'70' Essential messages X'80' Messages requiring immediate operator action X'F0' Extremely important messages` AS/400, JES3 and POWER set the importance level to X‘70’, but do not use it. RSCS does not use the importance level. The importance level is set to X‘70’ for notify messages and sets it to X‘30’ for command responses.
NMRPRIO	1	.4	bits	0	none	The output priority. AS/400, JES3 and POWER set the output priority to X‘07’, but do not use it. RSCS sets the output priority to X‘07’.
NMRTYPE	2	1	byte	0	none	Flag byte.
bit NMRTYPEX		.4	F0 bits	0	none	Reserved for IBM's use.
bit NMRTYPE4		.1	08 bit	0	none	If on, the sending userid is included in NMRMSG.
bit NMRTYPET		.1	04 bit	0	none	If on, the timestamp is not imbedded in NMRMSG.
bit NMRTYPEF		.1	02 bit	0	none	Not used for NMRs that contain a message.
bit NMRTYPED		.1	01 bit	0	none	If on, the NMR contains a delete operator message (DOM) request. DOM is a function of Multiple Console Support (MCS). This bit is not set or used by any system.
NMRML	3	1	binary	1	1-148	Length of the information in NMRMSG, including the userid if it is present. It does not include the timestamp if it is present.
NMRTO	4	9	mixed	none	none	The following two fields describe the destination node and system identifier for the command.
NMRTONOD		8	char	blanks	none	The destination node for the message.
NMRTOQUL	C	1	binary	0	none	The qualifier for the destination node. AS/400, RSCS and POWER set but do not use the qualifier code.
NMROUT	D	8	char	zeros	none	The destination userid, remote id, or console id depending on the setting of NMRFLAG.
NMRUCM	D	1	binary	0	none	This field contains the MCS console identifier when NMRFLAGU is set. AS/400, JES3, RSCS, and POWER do not use or set this field.
NMRUCMA	E	1	binary	0	none	This field contains the MCS console area when NMRFLAGU is set. AS/400, JES3, RSCS, and POWER do not use or set this field.
NMRLINET	F	2	binary	0	none	The line spacer for a multi-line WTO when NMRFLAGU is set. AS/400, JES3, RSCS, and POWER do not use or set this field.
NMRDESC	D	2	binary	0	none	This field contains the MCS descriptor codes when NMRFLAGT and NMRFLAGU are not set. AS/400 and JES3 does not use or set the field for messages. RSCS does not use the descriptor codes because it does not use MCS. POWER sets the descriptor codes to X‘0800‘ if a destination userid was not specified.
NMRROUT	F	2	binary	0	none	This field contains the MCS routing codes when NMRFLAGT and NMRFLAGU are not set. JES3 does not set the routing codes for messages. When receiving an NMR that contains a message, this field may contain a JES3 console number. RSCS and POWER sets the field to X‘4100’ if the destination userid is not specified.
NMRCONID	11	4	binary	0	none	The extended console identifier. JES3 does not set or use the field.
NMRRMT	D	8	char	none	none	This field contains the remote name when NMRFLAGW is set. JES2 uses the form ‘Rnnnn’ for the remote name.
NMRUSER	D	8	char	none	none	This field contains the destination userid when NMRFLAGT is set.
NMRFM	15	9	mixed	none	none	The following two fields describe the originating node and the qualifier.
NMRFMNOD		8	char	blanks	none	The origin node.
NMRFMQUL		1	binary	0	none	The qualifier for the originating node. AS/400 sets this filed to the default value, but does not use it. JES3 sets but does not use the qualifier. RSCS and POWER do not use or initialize the field.
NMRMSG	1E	1 -148	mixed	none		May contain the following: 8 bytes that contain the timestamp when the message was issued. 8 bytes that contain the userid of the operator or user that sent the message. Up to 132 bytes of message text.
NMRECSID	1E	8	char	blanks	none	If NMRTYPE4 is set, this field contains the originating userid followed by the message text. Otherwise, this field does not exist. JES3 does not use or set the field. RSCS sets and uses the field for messages that originate from a VM user.
