Summary
Brackets are used to group elements. They can be matched pairs such as begin..end or parentheses, or they can be key words. Line start/end can be used for brackets, as can indentation. Matched brackets have the problem of dropping the closing bracket. Later brackets are seen as elements of the unclosed bracket delaying error detection until the end of text. Different brackets may have the same or differing functions. The elements enclosed by brackets may form a function call, a parameter list, a control block, a set, a constant list, etc. (cbb 5/80)
