Configuring bidirectional data support

Use the ctg.bidi.target.layout Java™ system property to enable right-to-left bidirectional (bidi) data support.

When right-to-left bidirectional (bidi) data support is enabled, bidi data in CHAR containers is converted from logical order to visual right-to-left order before the data is sent to CICS®. The data is converted back from visual right-to-left order to logical order when the data is returned from CICS to CICS Transaction Gateway. For more information about bidi data support, see Bidirectional data support.

To enable right-to-left bidi text support use one of the following methods:

For Client applications running in remote mode, start CICS Transaction Gateway with the Java system property ctg.bidi.target.layout set to RTL. For example:
```
ctgstart -j-Dctg.bidi.target.layout=RTL
```
For Java Client applications running in local mode, set the Java system property ctg.bidi.target.layout to RTL. For example, the system property could be set as follows:
```
java -Dctg.bidi.target.layout=RTL application
```

If you start CICS Transaction Gateway without the system property option described above, by default, bidi data support is off. However, you can explicitly turn off bidi support by specifying -

Dctg.bidi.target.layout=OFF
