FALSE (-- falseCondition)

Inputs

• None.

Outputs

• falseCondition: FALSE condition constant.

This builtin has no inputs. It always pushes the known Cond value FALSE.

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

Behavior

• The result is known at compile time.
• The result schema is Cond.
• The pushed value is always FALSE.
• 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

2
