When building a load module with CALLLIBS, SMP/E may first need to link-edit the "base" version of the load module into the SMPLTS data set before link-editing the load module into its true target libraries:

• If the UPGLEVEL subentry exists for the set-to zone, a load module should exist in the SMPLTS data set only if it has both CALLLIBS subentries and an XZMOD subentry, indicating that at least one cross-zone module was linked into the load module. Therefore:
  • For a load module with CALLLIBS, but with no XZMOD subentries, SMP/E rebuilds the load module from scratch and links the rebuilt load module into its true system libraries by passing the CALL parameter with a SYSLIB data set allocated using the load module's CALLLIBS subentries. Typically, SMP/E does not link-edit the load module into the SMPLTS, although it may need to create a temporary member in SMPLTS to resolve certain warning conditions identified by the binder. This temporary member (if created) is deleted from the SMPLTS after a successful link-edit into the target library.
  • For a load module with both CALLLIBS and XZMOD subentries, SMP/E first looks for the "base" version of the load module in the SMPLTS data set. If the load module does not exist in the SMPLTS, SMP/E rebuilds the "base" version of load module from scratch and saves it in the SMPLTS data set. SMP/E next links the load module into its true system libraries by including the "base" version from the SMPLTS and passing the CALL parameter with a SYSLIB data set allocated using the load module's CALLLIBS subentries.
• If no UPGLEVEL subentry exists for the set-to zone, SMP/E first looks for the "base" version of the load module in SMPLTS. If the load module does not exist in the SMPLTS data set, SMP/E rebuilds the load module from scratch and saves it in the SMPLTS data set. SMP/E next links the load module into its true system libraries by including the base version from the SMPLTS and passing the CALL parameter with a SYSLIB data set allocated using the load module's CALLLIBS subentries.
