Everyone says it's the same thing with many lines.
Read mine:
Preset list of LETTERS
Dynamic Start End Points
Checks for existence of vars (You could do getRandomLetter(); with rkynicks and get a getSubStr error in console. error(); in v10 makes 4 lines in console :/)
Mine keeps to getRandomLetter. No one seems to understand that. I'd rather be able to do a script without having another 28 characters typed into it each time.
Pro-tip: $alphabet="abcdefghijklmnopqrstuvwxyz"; getrandomletter($alphabet);
another Pro-tip: getrandomletter(getsubstr($alphabet,3,12-3));(second number is the number you want to go to, minus the first number)
If you wanted simply getrandomletter() to work, you add ONE LINE. You do all this stuff WITH INSANE NUMBERS OF LINES.
if(%letters $= ""){%letters="abcdefghijklmnopqrstuvwxyz";}
Problem solved.
Advantages of mine:
Shorter and easier to edit(see: not overcomplicated)
Everything MegaScience listed off stupidly.
You can put in any text string to be searched for a random letter.
You can also use it to get random non-letters and such.
