Data conversion

The CICS® family of products runs on a variety of operating system and hardware platforms. Numeric and character data can be held in different ways in different systems. When intercommunication between CICS products requires the transfer of data, data conversion may be necessary.

This chapter gives an overview of data conversion that serves as an introduction to the task-oriented information in the CICS Intercommunication manual for your CICS product. It does not describe the mechanics of the process.

CICS products do most of the necessary data conversion automatically. Some conversion requires no setup by the user, for example, file names in function shipping requests. For other data, such as file records, you supply resource definitions that identify the types of conversion to be applied to specified fields in data records. For non-automatic conversion, exits or user-replaceable conversion programs are available in some products.
