Remarks:
The value of the variable needs to be passed as param "a" and the name of the variable as "aName". Typically one would write:
aVal := expr.VarByName[aName];
if Assigned(aVal) then //var was found

ShowHint := True;
Hint := expr.VarToolTip(aVal, aName);
end ShowHint := False;
The returned string will contain the name of the variable, its type and the value(s).
