Data-conversion exit reference

Data-conversion exit reference

For z/OS®, you must write data-conversion exits in assembler language. For other platforms, it is recommended that we use the C programming language.
To help you to create a data-conversion exit program, the following resources are supplied:

A skeleton source file
A convert characters call
A utility that creates a fragment of code that performs data conversion on data type structures This utility takes C input only. On z/OS, it produces assembler code.
For the procedure for writing the programs see:

Writing a data-conversion exit program for IBM® i
Writing a data-conversion exit program for IBM MQ for z/OS
Writing a data-conversion exit for IBM MQ on UNIX and Linux systems
Writing a data-conversion exit for IBM MQ for Windows

Skeleton source file
These can be used as your starting point when writing a data-conversion exit program.
Convert characters call
Use the MQXCNVC (convert characters) call from within a data-conversion exit program to convert character message data from one character set to another. For certain multibyte character sets (for example, UTF-16 character sets), the appropriate options must be used.
Utility for creating conversion-exit code

Valid syntax
Your input file for the utility must conform to the C language syntax.
