Name: DIRSHELL

Description:    This implements the user interface to the Multi-Edit dos shell.

Parameters:        /S=nn        Select type, where:
                                                0 = Normal DOS Shell
                                                1 = Invoked from the Load File prompt.
                                                            Should not load any files, just return
                                                            a file name in Return_Str.
                                                2 = Single directory, limited use.

                            All parameters below have defaults.
                            /X= Upper left corner X coordinate of directory list.
                            /Y= Upper left corner Y coordinate of directory list.
                            /W= Width of directory list.
                            /L= Length of directory list.
                            /D= Directory mask.  Defaults to *.*.

Returns:
                            Return_Int  If 1, load file was selected.
                            Return_Str  The last highlited directory entry

Global Strings:

                                archive program to generate the list for .ZIP files.
                                /D1=nn  The number of lines at the top of the list to
                                    delete.  This is to get rid of the startup message and

                                /D2=nn  The number of lines at the bottom of the list to
                                    delete.  This gets rid of any junk at the bottom.
                                /S1=nn  The number of lines at the top of the list to
                                    leave in but skip.  This is done after the deleting.
                                /S2=nn  The number of lines at the bottom of the list to
                                    leave in but skip.  This is done after the deleting.
                                /C=str  The command to user to run the program.  Must be
                                    the last parameter.
                             Example:
