You can display the contents of a .LIB library file using the LIB.EXE
library manager that comes with Microsoft QuickBASIC versions 4.00,
4.00b, and 4.50; with Microsoft BASIC Compiler 6.00 and 6.00b; and
with Microsoft BASIC Professional Development System (PDS) 7.00 and
7.10. The "listfile" argument for the library manager allows you to
specify the name of a cross-reference listing file. When you specify
the name CON, the listing will be displayed on the screen. You also
may output the list file to a disk file by specifying an output
filename.

To display the contents of a Quick library .QLB file, you may compile
and run the program QLBDUMP.BAS, which is located in the \SOURCE
subdirectory on release-disk 3 of QuickBASIC version 4.00 or 4.00b,
and in the subdirectory \EXAMPLES on the "Setup/Microsoft QB Express"
disk of QuickBASIC version 4.50. QLBDUMP.BAS is also included with
BASIC Compiler 6.00 and 6.00b and BASIC PDS 7.00 and 7.10.

The QLBDUMP program displays the contents of a .QLB Quick library.

The purpose of .QLB Quick library files is to resolve external routine
calls in the QB.EXE/QBX.EXE editor/interpreter environment at run
time. If you use a .QLB file, you must have a matching .LIB file if
you want to use the Make .EXE File option.

.LIB files are used by the LINK.EXE program to resolve external
routine calls at link time. LIB.EXE can display the contents of a .LIB
file.

The cross-reference listing file output from LIB.EXE contains the
following lists:

1. An alphabetical list of all public symbols in the library. Each
   symbol is followed by the name of the module in which it is
   referred to.

2. A list of the modules in the library. Under each module name is an
   alphabetical listing of the public symbols defined in that module.

For more information on the LIB.EXE library manager, please refer to
pages 227 to 234 in the "Microsoft QuickBASIC 4.0: Learning and Using"
manual for versions 4.00 and 4.00b.

Note that a copy of QuickBASIC (QB.EXE) comes with Microsoft BASIC
Compiler versions 6.00 and 6.00b for MS-DOS.
