How do I change doom's lower raise weapon behavior?

How can I make the doom cycle through each weapon just like quake1 and not have the typical lower and raise behavior when cycling through the different weapons?

Thanks guys!!!!!

If you're using ZDoom I'm pretty sure all you need to do is put something like this into a blank lump called DECORATE in a new wad(using the pistol as an example):

actor QPistol : Pistol replaces Pistol
{
  Game Doom
  Weapon.SelectionOrder 1900
  Weapon.SlotNumber 2
  Weapon.AmmoUse 1
  Weapon.AmmoGive 20
  Weapon.AmmoType "Clip"
  Obituary "$OB_MPPISTOL" // "%o was tickled by %k's pea shooter."
  +WEAPON.WIMPY_WEAPON
  Inventory.Pickupmessage "$PICKUP_PISTOL_DROPPED" // "Picked up a pistol."
  States
  {
  Ready:
    PISG A 1 A_WeaponReady
    Loop
  Deselect:
    PISG A 0 A_Lower <make sure this is 0
    Loop
  Select:
    PISG A 0 A_Raise <this too
    Loop
  Fire:
    PISG A 4
    PISG B 6 A_FirePistol
    PISG C 4
    PISG B 5 A_ReFire
    Goto Ready
  Flash:
    PISF A 7 Bright A_Light1
    Goto LightDone
    PISF A 7 Bright A_Light0
    Goto LightDone
  Spawn:
    PIST A -1
    Stop
  }
}

I haven't tested this myself though. The following method works in non-ZDoom ports but it makes switching between the Shotgun and SSG very touchy:

Copy that into a new text document, rename it to a .DEH file and run it with any DEH supporting port.

Thanks you guys are the best!!!!
