User Manual

<newname> is the new name to be used in renaming a group, address space, or segment;
the name of the group in which an address space is to be moved; or the name of the
address space in which a segment is to be moved.
The linker recognizes the special space NULL . NULL is not one of the spaces that an object
file or library can reside in. If a segment name is changed to NULL using the CHANGE
command to the linker, the segment is deleted from the linking process. This can be useful
if you must link only part of an executable or not write out a particular part of the execut-
able. The predefined space
NULL can also be used to prevent initialization of data while
reserving the segment in the original space using the COPY command. See also the exam-
ples for the
COPY command (see the COPY section on page 349).
Examples
To change the name of a segment (for example, strseg ) to another segment name (for
example, codeseg ), use the following command:
CHANGE strseg=codeseg
To move a segment (for example, dataseg ) to a different address space (for example,
EDATA), use the following command:
CHANGE dataseg=EDATA
To not allocate a segment (for example, dataseg ), use the following command:
CHANGE dataseg=NULL
COPY
The COPY command is used to make a copy of a segment into a specified address space.
This is most often used to make a copy of initialized RAM (RDATA, EDATA) in ROM so
that it can be initialized at run time.
