Using the IBM z/OS conversion environment and services

This procedure establishes the necessary IBM z/OS conversion environment.

Create an IMAGE member using the CUNMIUTL IBM image generator utility.
Copy the created image, member CUNIMG01, from WORK.IMAGE to SYS1.PARMLIB.
Load the image, member CUNIMG01, into z/OS using the SET UNI=01 command.
The DISPLAY UNI, ALL command displays the current active image and the character set conversions defined for that image.

To enable Client Option Unicode support, set the USEIBMUNICODE configuration parameter to Y. The USEIBMUNICODE is specified in the SYGWMCST macro in the SYGWXCPH customization module. The Client Option uses the newly defined unichar, univarchar, and unitext internal datatypes and performs conversions between UTF-8, UTF-16, and other CCSIDs.

For information on installing Unicode support for IBM z/OS, see “Support for Unicode Using Conversion Services” (SA22-7649-01).
