Zombies randomly play one of three different sound effects when A_Scream is invoked

A_Scream is a code pointer used in the death animation for various monsters.

A_Scream's main purpose is to play the monster's death sound. However, it includes a few minor tweaks:

Monsters using the zombie death sounds (DSPODTH1, DSPODTH2, DSPODTH3) will randomly pick one of the three. This ensures variation as not all zombies sound the same when they die.
Imps will randomly play DSBGDTH1 or DSBGDTH2 for the same reason.
The Cyberdemon and Spider Mastermind play their death sound effects at full volume when they die.

The A_Scream code pointer appears in the following states in Doom's state table:

Frame number	Doom internal name	Use
190	S_POSS_DIE2	death animation for the Trooper
223	S_SPOS_DIE2	death animation for the Sargeant
272	S_VILE_DIE2	death animation for the Archvile
347	S_SKEL_DIE3	death animation for the Revenant
389	S_FATT_DIE2	death animation for the Mancubus
423	S_CPOS_DIE2	death animation for the Chaingun Sargeant
458	S_TROO_DIE2	death animation for the Imp
491	S_SARG_DIE2	death animation for the Spectre and Demon
511	S_HEAD_DIE2	death animation for the Cacodemon
543	S_BOSS_DIE2	death animation for the Baron of Hell
572	S_BOS2_DIE2	death animation for the Hell Knight
596	S_SKULL_DIE2	death animation for the Lost Soul
621	S_SPID_DIE1	death animation for the Spiderdemon
653	S_BSPI_DIE1	death animation for the Arachnotron
692	S_CYBER_DIE2	death animation for the Cyberdemon
715	S_PAIN_DIE2	death animation for the Pain Elemental
745	S_SSWV_DIE2	death animation for the SS Nazi
766	S_COMMKEEN3	death animation for Commander Keen
809	S_BEXP2	death animation for the Barrel

The following is an example of how to set the A_Scream code pointer in a Dehacked file:

Pointer 21 (Frame 34)
Codep Frame = 809

Or using BEX syntax:

[CODEPTR]
Frame 1234 = Scream
