You can use HP Link Editor/XL to create and maintain executable library files (XLs). XLs contain executable modules with the following
characteristics:
Are in a form that can be directly executed.
Are shared, so that only one copy of the code need exist on the system. Programs that use an executable module share the same physical copy of the code.
Have their own global data, separate from the program's global data.
Have external references between executable modules and calling programs resolved at run time.
Cannot have outer blocks and are, thus not independently executable.
HP Link Editor/XL creates an XL by linking relocatable
object files or modules and
placing the resulting modules in a library file.
To be functional, an XL must be loaded with an executable program
file containing an outer block and an entry point.
MPE/iX executable libraries (XLs) have the following characteristics:
They can have any valid MPE/iX file name.
Many can be accessed in one command because you can specify several in the XL= parameter of :LINK or :RUN.
Creating an XL is a process similar to creating a relocatable library (RL); build an empty XL and add modules to it. For example, the commands
:LINKEDIT
LinkEd> BUILDXL MYXL
LinkEd> ADDXL FROM=MYOBJ
LinkEd> EXIT
|
enter HP Link Editor/XL,
build a new XL named MYXL, add the contents of a
relocatable object file named MYOBJ to it, and exit HP
Link Editor/XL.
For detailed information on manipulating an XL, refer to
Link Editor/XL Reference Manual (32650-90030).
HP Link Editor/XL automatically pre-links relocatable object modules as
you add them to an XL.
XLs are not searched at link time, but you can specify a list of
them for the loader to search when the program is run.
MPE/iX system libraries are XLs.
The loader automatically searches system libraries after any
libraries you specify at load time.
