Using Search Paths with Libraries
You can direct link to search directories and disk drives for the
libraries you have named in a command by either specifying one
or more search paths with the library names, or by assigning the
search paths to the environment variable LIB before you invoke
link Environment variables are explained under the set com
mand in Chapter 3, "ms-dos Commands."
A search path is the path of a directory or drive name. You type
search paths along with library names on the link command line
or in response to the Libraries prompt. You can also specify up to
16 search paths and assign them to the LIB environment variable
by using the ms-dos set command. In the latter case, you must
separate the search paths by semicolons (;).
If you include a drive or directory name in the filename for a
library in the link command line, the linker searches there only.
If you don't give a drive or directory name, link searches for
library files in the following order:
Q] First, the linker searches the current drive and directory.
[U If the library is not found and one or more search paths have
been given in the command line, the linker searches the speci
fied search paths in the order in which you gave them.
[H If the library is still not found and you have set a search path
by using the LIB environment variable, the linker searches
there.
El If the library is still not found, link prints an error message.
Examples:
In the first example, the linker searches only the \altlib directory
on drive A to find the math, lib library. To find common, lib, it
will search the current directory on the current drive, the current
directory on drive B, and finally the \ lib directory on drive D:

In the second example, link searches the current directory, the
\lib directory on drive C, and the \system\lib directory on
drive U to find the libraries, math, lib and common, lib:
set LIB=C:\lib;U:\system\lib
link file,,file.map,math+common
