I found this construct in the Perl Cookbook:
$Current_Screen = param(".State") || "Default";
I thought it was really cool because if the value of param(".State") comes
back undefined, the $Current_Screen variable gets set to "Default".
So the other day I wanted to do something similar:
@somearray = @array1 || @array2;
... hoping that if @array1 was empty, @somearray would get the contents of
@array2. But it doesn't work -- @somearray gets (1).
Is what I'm trying to do possible using a single command? Or is an
if-then-else the only way to do it?
TIA.
