In order to make nice help screen at batch file, use of blank line is inevitable. I tried to do it with "echo" command in dos prompt of Windows XP but echo command looks it does not support this.

Displays messages, or turns command-echoing on or off.

ECHO [ON | OFF]
ECHO [message]

Type ECHO without parameters to display the current echo setting.

When I just use "echo" in batch file, it justs show the current echo mode is On or Off.
However, you can use "echo," which mean "echo" followed by "," will work properly. I'm not sure it will work with other operating systems, but I confirmed that it works at Vista and XP. Note: You can use ":", ".",";","=","+","[","]","/","\","/" instead of "," as well.

Below is the example of batch file which shows blank line in help memu.

@Echo Off

echo Remove VLANs from the Team with VLAN numbers.
