The following steps will guide you when trying to extract .OBJ
routines from QB.LIB, using the library manager LIB.EXE. QB.LIB is
provided on the QuickBASIC release disk.

The following information applies to QuickBASIC Versions 4.00, 4.00b,
and 4.50, to Microsoft BASIC Compiler Versions 6.00 and 6.00b for
MS-DOS and OS/2, and to Microsoft BASIC PDS Version 7.00 for MS-DOS
and MS OS/2.

1. Get a cross-reference listing file of QB.LIB to identify the name
   of the routine to be extracted. You can do this by using the
   library manager LIB.EXE as follows:

   LIB QB.LIB,listfile;

   If "CON" is used as the name of the list file, then the listing
   file will appear on the screen. The listing for QB.LIB looks like
   the following:

   ABSOLUTE..........absolute          INT86OLD..........int86old
   INT86XOLD.........int86old          INTERRUPT.........intrpt
   INTERRUPTX........intrpt

   absolute          Offset: 00000010H  Code and data size: cH
     ABSOLUTE

   intrpt            Offset: 000000e0H  Code and data size: 107H
     INTERRUPT         INTERRUPTX

   int86old          Offset: 000002a0H  Code and data size: 11eH
     INT86OLD          INT86XOLD
     ABSOLUTE

   intrpt            Offset: 000000e0H  Code and data size: 107H
     INTERRUPT         INTERRUPTX

   int86old          Offset: 000002a0H  Code and data size: 11eH
     INT86OLD          INT86XOLD

2. To extract one of the .OBJ routines, use the library manager
   command "*module-name", where module-name is the name of the .OBJ
   routine inside the library. The following is an example:

   LIB QB.LIB *intrpt;

   Once executed, a copy of intrpt will be placed in the working
   directory with the same name and .OBJ extension. Remember, the
   routines are listed in lowercase.

For additional Library Manager command symbols refer to Page 231 of
the "Microsoft QuickBASIC: Learning to Use" manual.

The Library Manager (LIB.EXE) is provided with the QuickBASIC Compiler
Versions 4.00 and later; however, it is not provided with QuickBASIC
Versions 3.00 and earlier versions. LIB.EXE is also provided with the
Microsoft Macro Assembler.
