I make it for you with ZCMD and SScanf:

pawn Код:

CMD:Ban( playerid, params[ ] )
{
    new Player, str[ 128 ];
    if ( sscanf( params, "u", Player ) ) return SendClientMessage( playerid, 0xE60000AA, "USAGE: /Ban [PlayerID]" );

    Ban( Player );
    format( str, sizeof( str ), "SUCCES: {FFFFFF}You have banned ID: %d", Player );
    SendClientMessage( playerid, 0x00FF00FF, str );
    return 1;
}

What's hard at this?
