Arrays: Selecting data at random

[dangerousbrian]

I'm working on a word game now...  I need to  take a string & store each letter which the below code does quite nicely. (Just storing the ASC codes in case I find I need them)
   
s$="OLDENBURG HOTEL"
 ans=Len(s$)
 Dim letval(Len(s$)):Dim char$(Len(s$))
 For lp =1 To Len(s$)
    c$=Mid$(s$,lp,1)
    char$(lp)=c$
    letval(lp)= Asc(c$)
    ;Print letval(lp):Print char$(lp)
      Next lp

But now I need to go onto a blank screen & pop the individual letters up (in their right place!) at 10sec intervals for a 'guess the word' game. Can I access an array & take random info out (and on the next pass make sure it doesn't grab a letter thats already been selected & displayed?)
Alternatively I could just scramble the letters & print the new string, but I still need to grab them at random........

You mean text that get's put onto the screen slowly? Like on many, many games? Well I almost had it once, but for some reason GetStringWidth() wasn't making the letters go into the correct places

I'll see if I can hack something up later, oh, and intenting your code might prove very useful when trying to read it

Thanks for your help Draco. If you run the code below you'll see what I'm trying to do. (ignore the print command in the first loop, it was just there so I could see that things were working). When the "??????? ??????" screen comes up I then want to replace, one at a time, at 10sec intervals or on a keypress the ? with a letter.
Don't know what you mean about intenting?
