This chapter describes:
You can control your program's execution sequence by constructs containing statement blocks and other executable statements that can alter the normal execution sequence, as defined under Order of Statements and Execution Sequence. The construct descriptions in this chapter do not provide detailed syntax of any construct statements; rather, references are made to the "Statements" section.
If a construct is contained in another construct, it must be wholly contained (nested) within that construct. If a statement specifies a construct name, it belongs to that construct; otherwise, it belongs to the innermost construct in which it appears.
