Linking Files Linker Command File

LINKER COMMAND FILE

The linker command file is text file that contains the linker command and options. The linker

commands that can be used in the command file are summarized in

Table 3-3. For linker

options see Table 3-4.

NOTE: The linker commands are listed alphabetically in the table, for convenience; however, it is not

required that commands be specified alphabetically in the command file. Command words and param

eters other than those shown in the table are not legal. If any other word or parameter is used, an error

message is written to the messages file, and the linker terminates without linking anything.

The <section> must be a control section name, and the <address-space> must be an address

space name.

Example: ASSIGN DSEG DATA

Linker Command COPY

This command makes a copy of a control section. The control section is loaded at the speci-

fied location, rather than at its linker-determined location. This command is designed to
