NPC randomize A-Z letters for maximum of 30 letters?

[Currently]

Will it be possible for an NPC to randomize A-Z letters in maximum amount of 30 letters?

Then, the player will hunt have to type that random letters?

setarray .@ww$,"A","B","C", ... , "Z";

{
set .@www$,.@www$+.@ww$[rand(26)];
}

by "loop" do you mean i copy-paste this part "setarray .@ww$,"A","B","C", ... , "Z";" 30 times?

setarray .@ww$,"A","B","C", ... , "Z";

setarray .@ww$,"A","B","C", ... , "Z";

setarray .@ww$,"A","B","C", ... , "Z";

all the way down to 30? sorry kinda confuse. or am i suppose to just copy paste your script?
