I worked around the issue with an untidy kludge in QUIZ. Thanks to
Donna for providing a most interesting CI script, with which I will
implement a more satisfactory solution.

The problem with using simple algebra with the CI VARS that HP
provides is of course deriving a valid date from the result.

:SETVAR HPDD 20
:SETVAR TOMORROW,!HPDD + 1
:SHOWVAR TOMORROW
TOMORROW = 21
:SETVAR HPDD 31
:SETVAR tomorrow,!HPDD + 1
:SHOWVAR TOMORROW
TOMORROW = 32

Ooops!

A function or utility to calculate valid dates is sort of what I was
hoping the operating system or one of its utilities would provide. I
would rather not have to do that myself.  The script that Donna so
kindly provided reveals just how much work that is.

I am surprised to discover that this sort of thing does not appear to
be provided for in the CI.  Even the 'POSIX' date utility in HPBIN
lacks the capability.
