Processing Multi-line WTO Messages

Each line of a multiline WTO appears on the Event Management console of the target node if the mlwto optional parameter is specified in the DEST.DAT file for the driver. Other messages on the console can interrupt the lines (major and minor). The Category field in the Message Record is used to tie the lines together.

If these messages require processing on the target node, the contents of the Category field provides the information to associate the lines of the multiline WTO.

The Category field contains a WTO Descriptor that CAS9FEMS built. This field indicates whether the line is first, middle, or last. This field also contains a version number and the identifier that is supplied with the WTO in the mainframe syslog to link together all the lines of the multiline WTO.

The format of the 12-byte WTO descriptor is as follows:

VVIIIIIIIIXY

VV

Indicates the 2-byte version '01'.

IIIIIIII

Indicates the 8-byte decimal character representation of the 3-byte binary message ID given to the MPF exit CATNMPEX by z/OS. The last three characters are displayed in the mainframe log to tie the lines of the WTO together.

X

Indicates the line-order, one of the following characters to indicate the order of the line:

• O - only one line (single-line WTO)
• F - the first line of an MLWTO
• M - the middle line of an MLWTO
• L - the last line of an MLWTO

Y

Indicates the line-type, one of the following characters to indicate what type of line:

• D - for data
• C - for control
• L - for label
• E - for end
• ? - for other
