Customizing Fortran LIBPACKs

The Fortran LIBPACKs are collections of individual modules that are packaged into a single load module in order to reduce the time that would otherwise be needed to load the individual modules.

Language Environment provides four Fortran LIBPACKs, which you can customize either during or following the installation of Language Environment.

Table 1. Fortran LIBPACKs
For applications link-edited with…	Customize LIBPACK…	Which is loaded…
Language Environment	AFHPRNAG	Above 16 MB
Language Environment	AFHPRNBG	Below 16 MB
VS FORTRAN	AFH5RENA	Above 16 MB
VS FORTRAN	AFH5RENB	Below 16 MB

The following tables give the names of the individual modules that can be included with or excluded from the LIBPACKs. In the tables, the terms required and optional are defined as follows:

required: Means that this module must be a part of the LIBPACK. It is not possible to exclude it.
optional: Means that this module may be either included or excluded from the LIBPACK. If the function indicated for the module is frequently used at your installation, the module should generally be included in order to avoid having to load it individually for each enclave.

For LIBPACKs loaded above the 16-MB line, the optional modules are included in the IBM-supplied default LIBPACK. For LIBPACKs loaded below the 16-MB line, only the required modules are included in the IBM-supplied default LIBPACK. Each optional LIBPACK module is also present individually. It will be loaded if that module is not included in the LIBPACK.
