Setting Up a Multi-Modeling Environment › Shared Name Environment › Object Prefixes

Object Prefixes

For a shared name environment, we recommend that you assign an object prefix to shared objects. Program YALCVNMR1R assigns the object prefix using the SYS entry in the YALCVNMRFP file. All models in the environment then share the prefix.

Note: The source for the YALCVNMR1R name allocation program is shipped in source file QRPGSRC in library Y2SYSRC.

If you want object prefixes to indicate the model origin of each object, you need to assign prefixes differently. A typical method is to create a new data area for the prefix in each model. Change the YALCVNMR1R program to retain the data area rather than to access the file. The library list then determines the object prefix.

Note: For environments with many objects, you may need to reset the YALCVNMRFP file.CA 2E then starts allocating object names from the next prefix. Make sure you allocate unique prefixes for each model. It is possible to assign duplicate names.CA 2E implements the names until no duplicates exist for the current model, but does not check the models for duplicates.
