Overview:

This C/370 library provides methods to serialize/deserialize complex messages.

With the advent of CICS containers, z/os programs can now receive multiple named structures and produce multiple named structures.

LegStar supports this multiple input/multiple output message exchange protocol with a notion of message parts.

The LSMSGLIB library helps transforming message parts into byte streams to be transported to clients. It also helps creating message parts from a byte stream received from a client.

LSMSGLIB shields transport handling programs such as LSMQHBIN or LSWEBBIN from complex message handling.

LSMSGLIB uses the LSCOMLOG also part of this delivery.

Limitations:

- LSMSGLIB has a limitation of 10 input message parts per complex message.

This program has been tested for:

- CICS TS 2.3 (6.3.0 Command language translator) and TS 3.1 (6.4.0)

- C/370 for OS/390 V2 R10

How to use:

Once LSMSGLIB is compiled in a library available to your CICS region in the RPL list, you might need to define it using RDO (unless programs get autoinstalled).

LSMSGLIB is not a standalone program.
