`my $value = (if condition? then this: else this);` [download] That's about the quickest explanation. Ternary should never be used in void context. See my node Ternary in void context where I cleared up my ternary confusion as well. The ternary operator always returns the value present in its truth branch (for lack of a better term), that's why you shouldn't substitute it for if then constructs. an if then construct that warrants a ternary is similar to the following `if($some_var eq 'X') { $this_var = 'Run using X format'; } else { $this_var = 'Run using standard format'; }` [download] This would equate to the ternary `$this_var = ($some_var eq 'X'? 'Run using X format':'Run using standar +d format');` [download] Grygonos	[reply] [d/l] [select]
