How do you rename your map in automap and in intermission?

That's the old format. Unless you are mapping for ZDaemon or Odamex, you should use the modern format. I translated it for you. This is for Doom 2, MAP01. Naturally, you will want to change stuff to fit your map.

map MAP01 "Entryway"
{
levelnum = 1
titlepatch = "CWILV00" // Include this line only if you are supplying a custom title image.
next = "MAP02"
secretnext = "MAP02"
sky1 = "SKY1", 0
cluster = 1
par = 30
music = "D_RUNNIN"
}
