    Standard Script Errors
**************************************************************************
    It is recommended that scripting components use the following set of error
    codes to signal failure when applicable.  This enables applications that
    use the OSA API to deal with some class of script errors in a less than
    ad hoc manner.  Scripting components are of course encouraged to return
    component-specific errors when these don't apply.
*************************************************************************}
{        Dynamic errors:

    These errors result from data-dependent conditions and are typically
    signaled at runtime.
}
{
        Signaled when a value can't be coerced to the desired type. Similar
          to errOSATypeError except results from coercion.

{
        Signaled by user scripts or applications when no actual error code
          is to be returned.  Simply means "an error has occurred".  Most useful
          in conjunction with an error message from the application.

    These errors comprise what are commonly thought of as parse and compile-

    OSA Interface Descriptions
**************************************************************************
    The OSA Interface is broken down into a required interface, and several
    optional interfaces to support additional functionality.  A given scripting
    component may choose to support only some of the optional interfaces in
    addition to the basic interface.  The OSA Component Flags may be used to
    query the Component Manager to find a scripting component with a particular
    capability, or determine if a particular scripting component supports a
    particular capability.

          expression.  This will cause the OSAGetSource call to return the error

          may not retain the source anyway.  This is mainly used when either space

          (kOSAModeNull) means to send events with kAECanSwitchLayer.  Supplying

        This is a mode flag for OSACompile that indicates that a context should

          This means that the previous script ID must designate a context.
          The presence of this flag causes the kOSAModeCompileIntoContext flag

        Makes a new empty context which may be passed to OSAExecute or
        OSAExecuteEvent.  If contextName is typeNull, an unnamed context is
        created. If parentContext is kOSANullScript then the resulting context
        does not inherit bindings from any other context.

        Errors:
            badComponentInstance    invalid scripting component instance

            errOSAInvalidID
            errAECoercionFail:        contextName is invalid
