Many years ago when I was programming in Delphi I used to have object arrays of size 2 and referencing to the element index with true and false. This was very very useful.
It was possible since false=0 and true=+1. In Gambas we have false=0 and true=-1. So now I came up with: Dim sMoods As String[] = ["Sad", "Happy"] Dim bHappiness As Boolean Debug CInt(True), Abs(True), Abs(CInt(True)) Debug CInt(False), Abs(False), Abs(CInt(False)) bHappiness = False Debug "bHappiness= "; bHappiness; ": " & sMoods[Abs(CInt(bHappiness))] Debug "bHappiness= "; bHappiness; ": " & sMoods[If(bHappiness, 1, 0)] bHappiness = True Debug "bHappiness= "; bHappiness; ": " & sMoods[Abs(CInt(bHappiness))] Debug "bHappiness= "; bHappiness; ": " & sMoods[If(bHappiness, 1, 0)] 1. Why is Abs(True) True? 2. Which is fastest, Abs(CInt(... or If(... ? I guess that If(... is more future proof. 3. I have a "BoolToIndex" function in a library module but I was thinking if it should not be part of the language, to be able to reference in a _simple_ way to an array element with a boolean. /Patrik ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
