Adding new modules to the target libraries

The SMP/E APPLY process can be used to install a SYSMOD that introduces a new module into the system libraries. To apply a module for the first time, SMP/E requires that the DISTLIB operand be specified on the ++MOD statement.

If the module is to be installed into an existing load module, this fact can be identified to SMP/E in two ways:

If no additional link-edit control statements (other than the INCLUDE statement) are required to rebuild the load module, the LMOD operand on the ++MOD statement can be used to indicate that the new module is to be link-edited into the existing load module. If no LMOD entry exists in the target zone for the specified load module, an error results.
If adding the new module requires the addition of a link-edit control card in order to rebuild the load module (for example, another ORDER card is required or a new ENTRY is established), inline JCLIN is required to redefine the load module structure.

If the module is part of a copied library, SMP/E already has all the information necessary to install the module fully; therefore, no special operands or processing is required. SMP/E uses the DLIB entry to determine that the distribution library has been totally copied, to build a new target zone MOD entry with a LMOD subentry equal to the module name, and to build a LMOD entry (with a name equal to the module name), using the SYSLIB value from the DLIB entry and the LEPARMs from the ++MOD LEPARMs.
