 Answer These Questions
------------------------------------------------------------------------------

     To help determine what the problem is, answer these questions:

     1. In what way does the application fail?

        Can you load the application at all?  If so, what behavior does the
        failing program exhibit?  Does your application display any error
        messages?  If so, what message and register values appear on the
        screen?

     2. Does PMINFO run?

        If you cannot run your program at all, try running PMINFO, supplied
        with CA-Clipper/ExoSpace.  If it runs, the problem is not likely to
        be a BIOS incompatibility.

     3. What resident programs are loaded on your system?

        You may have a device driver or some other software (like network
        software) that is incompatible with CA-Clipper/ExoSpace.  To
        determine whether the problem is caused by a software
        incompatibility, try running your application after unloading your
        network drivers or removing DEVICE= statements out of your
        CONFIG.SYS.

        If the CA-Clipper/ExoSpace program runs when the other program is
        removed, there is a compatibility problem.

        CA-Clipper/ExoSpace follows the DPMI, Virtual Control Program
        Interface (VCPI), and Extended Memory (XMS) protocols.  If the
        product that prevents CA-Clipper/ExoSpace from running follows one of
        these protocols, call Computer Associates Technical Support.  If it
        does not, refer to the Software Compatibility section in this
        chapter.

     4. What kind of a machine are you running on?

        If PMINFO does not run on your machine after you have removed other
        resident programs, your system or BIOS is not compatible with
        CA-Clipper/ExoSpace.

        If you are running on a machine that you think is AT-compatible, your
        system BIOS is probably not compatible with CA-Clipper/ExoSpace.  Run
        RMINFO to get the information about your system that you could not
        get from PMINFO (RMINFO does everything that PMINFO does, except
        attempt to switch to protected mode).

     5. How much available memory does your system contain?

        If the application fails with the message "not enough memory," your
        system may not have enough memory, or the memory may not be available
        to CA-Clipper/ExoSpace.  See the Memory Shortage section in this
        chapter.
