I was reading the DM guide and when certain examples of code were given that included var/something in a verb or proc, i was confused as to why it was included. ex.
view() << "A shimmering portal appears!"
view() << 'portal.wav'
make_portal(NewName as text)
-> var/obj/portal/P = new/obj/portal(usr.loc)
if(NewName) P.name = NewName
If you can please clarify this.
