What would be the following situation using if ternary ? 

if StrToInt(Edit1.Text) < 30 then
      Edit2.Text := '30'
   else if StrToInt(Edit1.Text) in [30..50] then
      Edit2.Text := '40'
   else
      Edit2.Text := '50'

v = StrToInt(Edit1.Text);

Edit2.Text = IfThen(v < 30, '30', IfThen(v in [30..50], '40', '50'));

In programming languages, the expression :? , is known to be a Ternary Operator , several languages

Delphi

However from Delphi7, there is the option to use IfThen : 

IfThen([Expressão boleana], [Se verdadeiro], [Se falso])

However, you can not do this: 

y:= IfThen(x <> 0, 1/x, 0);

Being necessary to use the traditional way: 

if x <> 0 then y := 1/x else y := 0;
