lookup with strings
getFnLookupString('info') getFnLookupString('warn') getFnLookupString('error') getFnLookupString('fatal') getFnLookupString()
lookup with number
getFnLookupN('1') getFnLookupN('2') getFnLookupN('3') getFnLookupN('4') getFnLookupN()
lookup in array
getFnLookupA(0) getFnLookupA(1) getFnLookupA(2) getFnLookupA(3) getFnLookupA()
