It does not seem possible with batch files. The apparent workaround it to write or find a console application which you could run from your batch file, but… does it pay of to bother about it? I don't think so? The batch files have considerable value if they can work in any system, without additional utilities, especially those written only for the purpose of extending batch functionality.

By the way, you can easily learn everything batch files can do. For this purpose, you can automatically build a help file on all topics related to batch file functionality on your system. To get it, you need to run this batch:

:: Version number for this batch file
SET MyVer=1.40
:: Display "about"
ECHO AllHelp.bat,  Version %MyVer% for Windows NT 4 / 2000 / XP
ECHO Generate an HTML help file for "all" available commands
ECHO Note:
ECHO This batch file uses the redirected output of the HELP command to generate the
ECHO HTML file. Because some commands use "special" characters like ^&, ^<, and ^> in
ECHO their help screen, not all output is displayed correctly in the browser.
ECHO Known issues: skipped ^<space^> "tag" in CMD's special character list and skipped
ECHO \^<xyz and xyz\^> word position references in FINDSTR's output.
