This is just a warning about this program. I e-mailed the author about it,
but he didn't reply and did nothing about it.

When you look at the source code of School Hours, you will see that the
program uses certain places in the system RAM to store its data (this
explains why the data remains on the calc if you overwrite School Hours
with  newer version). From a lot of those address, I don't know the exact
function (they are not listed in 82-RAM.txt and I couldn't find myself
what they were for). But from one address, I know that it's in the middle
of the Un real var (or was it Vn). This means that the schoolhours program
will mess up your parametric vars.

So I think it would be better not to use it instead of letting this
program do crazy stuff on your calculator.
