Introduction to Language Environment condition handling

This section outlines the Language Environment condition handling model in a POSIX(OFF) environment. It describes what constitutes a condition in Language Environment and how Language Environment supplements existing HLL condition handling methods. It also presents several condition handling scenarios to demonstrate how Language Environment condition handling works.

If you use mixed-language applications, it is especially important for you to know how Language Environment condition handling works with existing high-level language (HLL) condition handling schemes.

Described in detail later in this section are the steps involved in condition handling under Language Environment, HLL-specific condition handling considerations, Language Environment—POSIX signal handling interactions, and how you can communicate events that happen in a routine to another routine.

If your application is running under CICS®, you should refer to the CICS-specific condition handling information, which is discussed in Condition handling under CICS. If your application is running under IMS™, you should refer to the IMS-specific condition handling information, which is discussed in Condition handling under IMS.
