I was a bit surprised that the HP-71B is missing the PCOEF command of the HP-48G:

[-3 3 4 6]
PCOEF

[ 1 -10 15 90 -216 ]

The DATA statements provide the input. It's easier to change one or two numbers, add a number (then RUN the program) than to enter the whol list of roots again.

So we have to modify the program for every new set of data?
That's not very practical.
