A block is a sequence of declarations followed by a sequence of statements.
The declarations are optional.
The sequence of statements can be empty, but at least the
end-frame has to be present (in routines
end is allowed, too).
The key feature of a block is, that declarations are only valid while the statements are processed.
This concept is known as scope.
The following is a valid block:
const foobar = -1; type booleanArray = array of boolean; var check: booleanArray; begin check := booleanArray.create(true, false, true); end;
An indication, whether something constitutes a block, is, whether you can use it as part of a routine definition, as well as make a
program out of it (syntactically; apart from the terminating dot).
