AS100 Functions
Library File Referencing Function
If all of the following conditions are met, ln100 links relocatable modules entered in a library file.
Condition 1
Library file reference was specified on the command line.
Condition 2
After all specified relocatable module files have been allocated, some global labels remain
whose values are depending determination.
Precaution
The ln100 editor links the entire relocatable module where necessary global labels are defined.
Rules for referencing library modules
The ln100 editor determines the relocatable modules to be linked in the order described below. A
relocatable module that has been determined to be linked is relocated section by section. Sections
are relocated in the same way as sections are relocated in a relocatable module file.

The ln100 first searches the global label information of relocatable modules entered in a library
file. Relocatable modules are referenced in the order they are entered in the library file.
The labels searched from the library file are compared with the labels whose values are
pending. If any labels match, ln100 links this relocatable module in the library file to the
absolute module file.
After going over the relocatable modules in the library file, if there remains any global label
whose value is pending (i.e., a relocatable module in the library file contains an external
reference label), ln100 outputs an undefined error.
