Managing Model Objects › Working with Versions of Functions and Messages › Creating a Version

Creating a Version

You can create a new version of a function or message by using the:

• Work with Version panel
• Create Model Version (YCRTMDLVSN) command from within a control language program
• Create Object Version (YCRTOBJVSN) command outside control language programs

The new version will be a copy of the original function or message, but will have a different object name, object surrogate number, and implementation name. The object name for the version must be unique within the owning file; the implementation name must be unique within 3GL object type in the model. The new version is given the Copy name used by the version group to which it belongs.

To create a version from the Work with Versions panel:

Enter selection option 3 for the version you want to use as the source for the new version. You can select any version listed; it does not need to be the current version. The following panel displays:

1. Determine the To model object name. You can either let CA 2E generate a new name for the new version, or you can override this default.

   The name CA 2E generates is the original name suffixed by a 7-digit number; the original name is truncated if the new name is longer than 25-characters. For example,

   • Edit Branch 1459353
   • Edit Customer Addr1541577

   Note: You can define your own naming convention for automatic name generation using the exit program YOBJNAMR1C.

2. Determine currency. You can make the new version current by specifying *YES for the Make model object current option. The default is not to make the new version current so you can edit and test the new version before you make it current.

   If you do not make the version current at this time, you can do so later using option 26 on the Work with Versions panel or by using the Redirect Model Objects (YRDRMDLOBJ) command.

3. Determine whether to transfer the object name. You can request that CA 2E exchange the name of the original function or message with the name of the new version by entering *YES for the Transfer object name option. As a result, the name assigned to the original object will be the name indicated by the To model object name option. The default is not to exchange the names.
4. Press Enter to create the new version and return to the Work with Versions panel.

CA 2E adds the new version to your session list and creates a model object description for the new version. The Copy name assigned to the new version will be the Copy name currently being used for the group to which the new version belongs.

You can view the model object description for a non-current version using selection option 8 on the Edit Model Object List panel when editing your session list or any named model object list containing the version. By default only current versions are displayed when you edit the All Objects list (*ALLOBJ). To display non-current versions, press F17 and set the Current objects only option on the Subset Model Objects panel to *YES.
