Placing a list of items on the stack is actually very easy (only one shifted key more than individually loading them). Your program then simply needs to execute LIST→ instead of DEPTH to determine how many arguments were given.

I believe this is a small adjustment to make in comparison to the benefits to the user of not having to clear the stack first.

I second this method. One can also begin the program with

Code:


IF DUP TYPE 5. SAME THEN OBJ\->... (do whatever with multiple args)
ELSE... (use program-supplied defaults)

to allow either a single argument with the program supplying defaults, or some or all arguments supplied by the user.

For example compare UTPN on the HP 50 with NORMALD_CDF, its rough equivalent on the Prime.
