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

Is this what you’re trying to say?

my $EnvVar1 = ($EnvVar1 || "DefaultValue1");

my $EnvVar2 = ($EnvVar2 || "DefaultValue2");

my $Var3 = "$EnvVar1 -- $EnvVar2";

English:

If for some reason $EnvVar1 doesn’t have a value, use the value “DefaultValue1”

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