Setting bidirectional conversion support for an MVS system mapping

Developer for z/OS® provides special bidirectional properties for MVS system mappings to allow correct bidirectional layout conversions for files that are transferred between the client and server.

To set bidirectional conversion support for an MVS system mapping, do these steps:

1. Right-click a mapping criterion in the z/OS File System Mapping view
2. Click Edit.
   The Edit Data Set Mapping window opens.
3. In the Defined Language section, click Default to set bidirectional conversion options that are based on the Workstation file extension field or Other to select a language for the file extension.
   Bidirectional conversion in the Remote System Explorer is sensitive to the programming language in which source code is written. You can usually assume that the Workstation file extension field selects the correct language. In some cases, however, such as .cpy for COBOL and PL/I and .mac for PL/I and Assembler, the same file extensions can be used with different languages. Use the Other option to select a specific language to associate with the file extension.
4. Do one of the following steps:
   • To inherit the bidirectional settings from the MVS Files subsystem, click Inherit from properties for MVS Files. If the MVS Files subsystem uses a bidirectional conversion table, the name of the table is shown in parentheses and the properties that are inherited are shown in the Inherited set of bidi options table. For more information about property inheritance, see the related topics.
   • To use a bidirectional conversion table, do these steps:
     1. Click Use the following Bidi Conversion Table (BCT). This option enables the field and the Browse button.
     2. Enter the name of a bidirectional conversion file you created or click Browse to look for and select a conversion file.
     3. To edit the current properties in the bidirectional conversion table, click Copy. The properties are copied to the Current set of bidi options table, and you can click Edit to change the values and Save as to save your changes to a new bidirectional conversion table.
   • To use manual bidirectional settings, do these steps:
     1. Click Use the following manual bidi settings. This option enables a set of default bidirectional settings.
     2. Click Edit to open a window that you can use to change the default settings.
     3. Click Save as to save the current settings to a new bidirectional conversion table.
5. Click OK to apply the changes.
