[Krakuski]

the [50] and the [200] mean that they are the amount of letters or values you can put into a text..

Example:

pawn Код:

public OnPlayerConnect(playerid)
{
    new string[200]; //this means i can only have 200 letters
    format(string, sizeof(string), "SERVER: Welcome %s", RPN(playerid)); // in this line here
    SendClientMessage(playerid, 0xFFFFFFFF, string);
    return 1;
}
