 OS/2 Virtual DOS Machines
------------------------------------------------------------------------------

     CA-Clipper/ExoSpace programs can run in a Virtual DOS Machine within
     OS/2, Version 2.0 or later; this environment is a DPMI host.  Users may
     need to set one or both of the following parameters for the Virtual DOS
     Machine:

     .  DPMI_MEMORY_LIMIT

        This is set to 2 MB by default.  If your program needs more than
        2 MB, have your user specify a larger limit.

     .  HW_TIMER

        In order to get an accurate reading for PMINFO, turn the timer ON.

     Other parameters may affect your program behavior; this has more to do
     with the way OS/2 emulates DOS than it does with DOS extension.

     To access these parameters, follow this procedure:

     1. From the System/Command Prompt window, select the icon for the
        Virtual DOS machine.

     2. Bring up the menu (Shift+F10).

     3. Select Open >Settings from the menu.

     4. When the settings box opens, select Session from the tabbed options
        at the right.

     5. Select the DOS settings button.  The list of parameters will appear.

     For information about these parameters, please refer to your OS/2
     documentation.
