FALSE (-- falseCondition)

Inputs

• None.

Outputs

• falseCondition: FALSE condition constant.

It always pushes the known Cond object FALSE.

FALSE is one of the two fixed known Cond constants. The other fixed value is TRUE. The configuration-dependent known Cond object is DEBUG.

An operation whose result is described as FALSE yields a Cond object whose value is false. Such a result need not be known at compile time. printStack shows a known false Cond as FALSE and an unknown Cond as Cond.

Behavior

• Because the result is known, it drives compile-time condition handling directly.

Example

{} 0 {} [
  FALSE [1] [2] uif printStack _:;
  0
] "main" exportFunction

Expected Output During Compilation
