Relocatable Libraries
Relocatable libraries on both MPE V and MPE XL systems let you
efficiently organize code units. They are similar in that they contain a
collection of relocatable code units that are used during linking to
resolve external references.
The commands used to manipulate relocatable libraries under MPE V and MPE
XL have the following similarities:
* The ADDRL command adds code units to a relocatable library.
* The BUILDRL command creates a relocatable library.
* The LISTRL command lists the contents of a relocatable library.
* The PURGERL command deletes code units from a relocatable library.
* The HIDERL and the MPE V HIDE commands hide procedures.
Although HP Link Editor/XL and MPE V Segmenter manage libraries in a
similar fashion, they differ in noticeable ways. The following list
summarizes the differences:
