- 1. An IF placed inside the THEN or ELSE branch of another IF. It is only checked when that outer branch runs, and each IF needs its own ENDIF, with the inner ENDIF written first. Word 1 of: ______ IF (6)
- 2. A named block of code, written once, that runs whenever it is called. Procedures and functions are the two kinds, and they break a program into parts. (10)
