The Linkage Editor is an interactive, graphical editor for defining data items that are passed from a calling program (that is, Linkage items). Use the Linkage Editor to add, modify, or remove Linkage section data items. Items defined in this editor are generated into the program's .lnk COPY file (program.lnk). The entire contents of the .lnk file are recreated by AcuBench every time the program is generated. Never directly modify the file.
