Still simpler:

	address = substr(...   )
	if (address)
		print address

Or:
	# assign substring to adress and print if not empty
	if (address = substr(...   ))
		print address

BE WARNED: I explicitly wrote a comment in front of the if statement.
So don't start a discussion thread whether it is obscure, good, bad,
professional or whatever programming style to write assignments within
conditional contexts :-)
