Every application segment belongs to a named class such as "CODE,"
"DATA," or "BSS." LINK orders segments in the output file to place
segments that have the same class into the file contiguously. LINK
does not change the order of segment classes and, within each class,
LINK does not change the order of segments.
In an assembly language application, if a segment does not have a
class name, the linker assigns it to the null class, which is
processed as any other segment class.
If the linker command line includes the /DOSSEG option switch or
specifies a run-time library from a Microsoft language product, LINK
imposes the following order on the segments in the output file:
code - class names that end in "CODE"
far data - all segment classes except for "DGROUP" and code
DGROUP - (this segment is the default
data segment for the application)
- class "BEGDATA" (a special run-time segment)
- near initialized data (all data except
for "BSS" and "STACK")
- near BSS uninitialized data (class "BSS")
- stack (class "STACK")
