Forums mIRC Help %Server-Host %Server-Port

Hi guys, I found an alias written by someone else allows me to connect to my server -

sockopen client.sock %Server-host %server-port

But I, for the life of me, can't find where %Server-host and %server-port is being referred to. Can someone please explain these parameters to me and maybe point me to where I can find them.

I'm pretty new so if I'm not giving enough information, please ask. Thank guys it'll help me out.

Use ALT+R and select the Variables tab.

Thanks a bunch westor! That did it.
Think I'll stick with these forums, great response time.
