Рандомный вывод текста

[cccmertnik]

new mystring[264];
new rcode[][48] =
{
{"A","B","C","D","E","F","G"," H","I","K","L","M","N","O","P" ,"Q","R","S","T","V","X","Y"," Z"},
{"a","b","c","d","e","f","g"," h","i","k","l","m","n","o","p" ,"q","r","s","t","v","x","y"," z"}
};


new randc = random(sizeof(rcode));
format(mystring, sizeof(mystring),"%s",randc);

SendClientMessage(para1,COLOR_BODY_INTERFACE,mystring);

Почему не работает??
