In Windows NT, we had to use tip 0323 to accomplish this.

In windows 2000, you can use the

SET /P variable=\[promptString\]

"The /P switch allows you to set the value of a variable to a line of input
entered by the user.  Displays the specified promptString before reading
the line of input.  The promptString can be empty."
Here is a silly little example:
@echo off
set OK=N
set /p user=Please enter your User Name or END.    
if /i \[%user%\]<h1><a name="_END_endlocal_amp_goto_end_if_user_">\[END\] endlocal&goto end
if \[%user%\]</a></h1>\[\] goto again
for /f "Tokens=*" %%i in ('net user "%user%" /domain') do call :parse "%%i"
If "%OK%"<h1><a name="_N_goto_again_set_p_xxx_Press_any_key_to_exit_endlocal_goto_end_parse_set_ustr_1_if_not_ustr_1_9_">"N" goto again
set /p xxx=Press any key to exit.  
goto end
set ustr=%1
if not "%ustr:~1,9%"</a></h1>"Full Name" goto end
set ustr=%ustr:"=%
set ustr=%ustr:Full Name                    =%
@echo Thank you %ustr%
set OK=Y
