Do you have ZCMD included? This compiles just fine for me:

pawn Код:

#include <a_samp>
#include <sscanf2>
#include <zcmd>

enum pInfo
{
    Admin,
};

new PlayerInfo[MAX_PLAYERS][pInfo];

CMD:akill(playerid, params[])
{
    new target;

    if(PlayerInfo[playerid][Admin] < 1 && !IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xF50A0AFF, "<!> ERROR: You are not authorized to use this command!");
    if(sscanf(params, "u", target)) return SendClientMessage(playerid, -1, "/akill [ID/PartOfName]");

    SetPlayerHealth(target, 0);

    return true;
}

CMD:akillall(playerid, params[])
{
    if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, -1, "You're not an admin!");

    for(new i; i < GetMaxPlayers(); i ++) SetPlayerHealth(i, 0);

    return true;
}
