k    Random Number Generation (RAND)
u Random Number Generation (0 to 1) (Ran#, RanList#)
  Ran# and RanList# generate 10 digit random numbers randomly or sequentially from 0 to 1. 
Ran# returns a single random number, while RanList# returns multiple random numbers in list 
form. The following shows the syntaxes of Ran# and RanList#.
   Ran# [
a]   1  < a  < 9
   RanList# (
n [,a]) 1  < n  < 999
  •  
n  is the number of trials. RanList# generates the number of random numbers that 
corresponds to  
n  and displays them on the ListAns screen. A value must be input for  n .
  • “ 
a ” is the randomization sequence. Random numbers are returned if nothing is input for “ a ”. 
Entering an integer of 1 through 9 for  a  will return the corresponding sequential random 
number.
  • Executing the function Ran# 0 initializes the sequences of both Ran# and RanList#. The 
sequence also is initialized when a sequential random number is generated with a different 
sequence of the previous execution using Ran# or RanList#, or when generating a random 
number.
