Visual Basic .NET If(condition, valueIfTrue, valueIfFalse)
Python valueIfTrue if condition else valueIfFalse
S-Lang
FORTRAN 77
Forth condition IF valueIfTrue ELSE valueIfFalse THEN
OCaml match value with
    pattern1 -> expression
    |
    pattern2 -> expression
    ...
    «| _ -> expression»[a]
if condition then valueIfTrue else valueIfFalse
F#
Standard ML case value of
    pattern1 => expression
    |
    pattern2 => expression
    ...
    «| _ => expression»[a]
Haskell (GHC) case value of {
    pattern1 -> expression;
    pattern2 -> expression;
    ...
    «_ -> expression»
}[a]
select case conditional expression

^a This is pattern matching and is similar to select case but not the same. It is usually used to deconstruct algebraic data types.
