The Data-Conversion sample program

 

---

The data-conversion sample program is a skeleton of a data conversion exit routine. See Features demonstrated in the sample programs for the names of these programs.

 

Design of the data-conversion sample

Each data-conversion exit routine converts a single named message format. This skeleton is intended as a wrapper for code fragments generated by the data-conversion exit generation utility program.

The utility produces one code fragment for each data structure; several such structures make up a format, so several code fragments are added to this skeleton to produce a routine to do data conversion of the entire format.

The program then checks whether the conversion is a success or failure, and returns the values required to the caller.
