Hi there, On April 26 (12:00 -0000), David Genziuk wrote with possible deletions: | Is it possible to step through a hugs script, as in C where it is possible | to debug by stepping in and evaluate variables?

Keep in mind that, in Haskell, variables (in the C sense) do not exist. What you can do, though, is to observe intermediate results of (sub-)expressions in your Haskell program. This is what HOOD gives you (and more).
