It could be
$EnvVar1 and 2 are in fact not initialized and that is the
complaint.


Is this what
you&rsquo;re trying to say?


my $EnvVar1 =
($EnvVar1 || "DefaultValue1");
my $EnvVar2 =
($EnvVar2 || "DefaultValue2");
my $Var3 =
"$EnvVar1 -- $EnvVar2";


English:
If for some
reason $EnvVar1 doesn&rsquo;t have a value, use the value
&ldquo;DefaultValue1&rdquo;










Ah, this could be a good use of the "//" instead of
"||", right?
