The error msgs are not very informative IMHO.
Would you clarify please.

I must say that once again I find myself struggling to learn your
programming language. You have very detailed language specs, but
very few simple examples of everything possible. Newcomers to Seed7
have to hut and search and dig for examples at the rosettacode
site. That is /not/ good advocacy! It's too bad that this is the
situation, because you might have a popular and productive language
if there was a comprehensive tutorial to learn it from.

Anyway, if you could set me straight for my current issue, then I
might be able to keep on going. TIA ..
