I have no idea what this MAKELIST command does or how to handle lists on the Prime, but the implemented idea seems to calculate some kind of JDN.

However, I don't know if the line that checks whether a date is before or after 15 Oct 1582 (switch from Julian to Gregorian calendar) is correct. But this can be omitted anyway since in 1582 there was no Unix. At least as far as I know. ;-)

But again: You do not have to do this manually. IIRC since 2015 the Prime includes the required commands, e.g. DDAYS and DATEADD. Take a look at the manual.
