Rule-initiated EXECs initiated by MVS multiline or multisegment messages

To access the additional lines and segments in the MVS or IMS message, the EXEC must use the IMFEXEC VGET statement to read LOCAL variables for LINE1 through LINExxxx (depending on the number of lines of the WTO).

The actual number of lines or segments in the MVS or IMS message is stored in the TSO variable IMFNOL. If you have five lines, IMFNOL=5.

Potential use

This example shows how to access the additional lines of information from multiline WTOs or multisegment messages.

The following shows an MVS multiline WTO that fired a Rule-initiated EXEC:

Describing the example

In this example, the ARG statement does not contain any symbolic parameters because the first line of the message is retrieved from the LINE01 variable.

However, in general, the first line could also be retrieved by using symbolic parameters (such as in Rule-initiated EXECs). The example in this section demonstrates this process. The EXEC simply retrieves all lines of the  IEF450I message and writes the output of this message to the BBI-SS PAS Journal.
