Indeed, including my own programs, until recently.
But my strong impression, fuelled by comments from
Stata developers, is that Stata has to
work very hard to let you do that in your code.
This is what I was curious about. All of the discussion on syntax/style is fine - I think you'd find my code to be written as you prefer - it was just a strange occurrence as I often will enter these loops in the command line manually and I never thought it was a problem.
Why should something like:

if `n' > 0 {di "This"...}

not be safe/smart in one line? Just curious if I should change the way I code.
