LINK TECHNICAL REFERENCE
You can link files totaling one megabyte. The output file from
the linker (a run file) is not bound to specific memory addresses
and, therefore, can be loaded and executed at any convenient
address. The relocation information is a list of long addresses
that must change when the executable image is relocated in
memory. See "Long References" later in this chapter for an
explanation.
Definitions
The following terms describe some of the functions of the linker.
For definitions of segment, group, and class, see the "Basic Infor-
mation" section in Chapter 11.
• Alignment refers to byte, word or paragraph segment
boundaries. You specify the alignment in an assembly'
language program.
The byte alignment tells the linker it can start a seg-
ment on any byte boundary (one segment can immedi-
ately follow another). Word alignment tells the linker to
start segments only on even addresses. Paragraph align-
ment tells the linker to start segments only on 16-byte
boundaries.
• Combine Type is an attribute of a segment. It tells the
linker how to combine segments that have the same
name or it relays other information about the properties
of a segment. Combine types are: stack, public, private,
and common (see "How the Linker Combines and
Arranges Segments").
• Canonical Frame is the starting address of the first
segment in a group of segments. Offsets are calculated
from this address.
