 *** Description:
 When stepping through a program in BSL, the stepper shows current progress, 
 e.g., 
 0/3, 1/3, 2/3
 But since the step numbers start at 0, the progress only goes to (n-1)/n, and 
 not n/n when the user has stepped through the entire program.
 I didn't notice this situation, but my students did during class, which 
 became their first lesson in 0-based indexing (for better or worse).
 Thanks! Marc

That was a deliberate choice, though I could be convinced that it was the wrong 
one; I think I was trying to mirror the behavior of the current search 
command.

Any other opinions?

The search command got changed a little while ago, I think. :)

But I think you should got from 1/n to n/n. (The text search is a
little more complex because you can be before or after the first /
last hit.)
