how to run server

[Ash sav]

I have downloaded Tomcat 4.0 but I am little confuse how to start the server. Documentation says following.
"There are two techniques by which Tomcat 4.0 can be started:
* Via an environment variable:
- Set an environment variable CATALINA_HOME to the path of the directory
into which you have installed Tomcat 4.0."
So how do I have to set env variable? Can somebody tell me?

just type: set CATALINA_HOME=c:\jakarta-tomcat-4.0.1
or you can add the set command to your autoexec.bat
then run startup.bat from the tomcat bin directory.
