9 Link: A Linker
' ' In this chapter you'll learn:
■ How to create executable files with link
C\ ■ How to use link command options
■ How link creates programs
Introduction
The Microsoft® 8086 Object Linker (link) creates executable pro
grams from object files generated by the Microsoft Macro Assem-
y-v bier (masm) or by compilers for high-level languages, such as C or
Pascal. The linker copies the resulting program to an executable
(.exe) output file. You can then run the program by typing the
^. file's name on the msdos command line.
To use link, you must create one or more object files, then sub
mit these files, along with any required library files, to the linker
-~ for processing. Link combines code and data in the object files
' * and searches the named libraries to resolve external references to
routines and variables. It then copies a relocatable execution
image and the relocation information to the executable file. Using
(***) the relocation information, msdos can load the executable image
at any convenient memory location and then run it. Link can pro
cess programs that contain up to one megabyte of code and data.
r*\ This chapter explains how to use the linker to create executable
programs. It also defines each of the options you can use in a link
command line to control the linking process. Finally, it explains
f*} how link creates programs.
