Re: Random Character String

If this is the same rand function from the PC C, it should return a decimal
number between 0 and 1.  Something like 0.393838382  To use this to
get a number from 1 to n (like 1 to 100) the formula is
The integer of (x * n) + 1

In C would like like Number = Int(Rand() * 26) + 1
which would produce a number from 1 to 26.  You might have a little fun
getting this formula to work accuratly in RPG, but it should be good enough
for your purposes even with truncation that will most likely occur.
