===Simple select===

<lang babel>

"foo" "bar" 3 4 > sel <<

</lang>

Prints "foo" since '3 4 >' evaluates to false, which causes sel to remove "bar" from the stack.

===If-Then-Else===

<lang babel>

{3 4 >}

{"foo"}

{"bar"}

ifte

<<

</lang>

Prints "bar" because the first line is the "if", the second line is the "then" and the last line is the "else", and '3 4 >' evaluates to false.

===Conditional===

<lang babel>

({3 4 >} {"Three is greater than four" }

{3 3 >} {"Three is greater than three"}

{3 2 >} {"Three is greater than two" }

{3 1 >} {"Three is greater than one" })

cond

<<

</lang>

Prints "Three is greater than two", as expected.
