you could write everything into one string and then split it. So it
would like this:
subsection bc
set value = 0.5*x+y; x*y^2

Take a look here
http://stackoverflow.com/questions/236129/split-a-string-in-c for some
ideas how to split a string.
Yes, this is the way to go. In fact, we have a function that splits strings:
https://www.dealii.org/8.4.0/doxygen/deal.II/namespaceUtilities.html#a8d799bb35ac16d206818c88e82afbfae
We use the scheme Bruno proposes to split strings first by semicolon,
and then again by comma all the time in our own projects. If you don't
like semicolons/commas, any other choice of course also works.
As far as working with people who are not used to programming -- this is
a tricky question. It is true that you need to provide a way that's
readable, but using work-arounds like have multiple sections is also not
entirely obvious and will invite questions whose answers you also have
to document somewhere. It is a balance that's sometimes difficult to
strike. I typically strive for a solution that is easiest to describe
and easiest to understand *in its entirety*. In your case, I would
probably choose splitting on semicolons and colons, and in the
documentation show how you can split different, semicolon-separated
parts of the formula onto separate lines using a backslash at the end of
the line to show that that makes formulas easier to read.
