 Packages
------------------------------------------------------------------------------

     CA-Clipper/ExoSpace contains a number of built-in packages which provide
     protected-mode support for certain low-level operations.

     Important!  You never need to use these packages in an application
     consisting purely of CA-Clipper code that does not use any third-party
     libraries.  However, some third-party libraries that perform low-level
     operations--such as direct screen I/O, mouse handling, or certain types
     of network calls--may require one or more of these packages to be
     included.  If you are using a third-party library that does not appear
     to operate correctly with CA-Clipper/ExoSpace, consult the vendor of
     that library to determine whether it requires any packages to be
     included when linking with CA-Clipper/ExoSpace.

 Mouse Support

     Any program or third-party library which supports a mouse will require
     that the MOUSE package be included when linking.  Failure to include
     this package will lead to unpredictable behavior, including applications
     that abnormally terminate or even hang.

     Packages can be specified using the EXOSPACE PACKAGE command when
     linking with CA-Clipper/ExoSpace.  For example, to include mouse and
     NETBIOS support in an application, your link script might include the
     following statement:

     EXOSPACE PACKAGE MOUSE, NET5C

     The following packages are available:

                information about the NOVM option.
