Making Entry Name Map Files Available to the Run-time System

You use the entry_name_mapper tunable to indicate to the run-time system that you want to use entry name mapping. If entry_name_mapper is set, how the run-time system searches for entry name map files depends on whether the ENTRYNAMEMAP environment variable is set:

• If ENTRYNAMEMAP is set, the run-time system searches in the semi-colon delimited list of folders and entry name map files it specifies. For each folder specified, the run-time system looks for an entry name map file called mfentmap.dat.
• If ENTRYNAMEMAP is not set, the run-time system searches for an entry name map file called mfentmap.dat in each folder specified by the COBDIR environment variable.

In either case, the run-time system could find more than one entry name map file, which means that the same entry point could be defined differently in different files. If this happens, precedence is given to the definition in the entry name map file that was found first. To change the order in which the run-time system finds entry name map files you need to change the order in which the files appear in the COBDIR or ENTRYNAMEMAP environment variable paths.
