This is an old thread that was resurrected, but what I do is to use Set.
Set "CountryTag" "us"
Set "LanguageTag" gb_en"
then later
OutputTo "COUNTRY"
IfOutput "CountryTag"
SayOutput "CountryTag"
EndIf
OutputTo "SUPPORTED LANGS"
SayOutput "LanguageTag"
to avoid them written to the files or reset them to be false
Set "CountryTag"
Set "LanguageTag"
