Processing Multi-line WTO Messages

Each line of a multi-line WTO will appear on the Event Management console of the target node if the mlwto optional parameter is specified in the DEST.DAT file for the driver. The lines (major and minor) may be interrupted by other messages on the console. 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 needed to associate the lines of the multi-line WTO.

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

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

VVIIIIIIIIXY

VV

Indicates the two-byte version '01'.

IIIIIIII

Indicates the eight-byte decimal character representation of the 3-byte binary message ID given to the MPF exit CATNMPEX by z/OS. The last 3 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 a MLWTO
• M - the middle line of a MLWTO
• L - the last line of a 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

For more information, see the IBM documentation on the WTO MACRO for line type and line type referenced above.
