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. 2-17
