Above needs Copy to NOT copy zero-length files - Win NT, DOS 6.1, 6.3.
The following fragment shows an alternative technique for processing the
result of "Find" :

        del b.bat
        del current.bat
        echo. | date | find "198" > b.bat
        echo date > current.bat
        call b
        del b.bat
        del current.bat
