Enums are somewhat better.
for example:

pawn Код:

enum pInfo
{
Vip
}
new PlayerInfo[MAX_PLAYERS][pInfo];

CMD:givemearmour(playerid, params[])
{
    if(PlayerInfo[playerid][Vip] >= 1)
    {
        SetPlayerArmour(playerid, 100);
    }
return 1;
}

Ofcourse, you should save it too. But i'm not going that deep to tell you now.
