Begin - end

"Begin" and "end" are used to designate blocks of code. A block consists of one or more statements that are combined to form a single new statement. This statement has the form:

        begin STATEMENT; STATEMENT; ... STATEMENT end

Note that statements within the block are separated by semicolons.

Each "begin" must have a matching "end". A common programming error is mismatched "begin-end" pairs.

Square brackets ([ ]) can be used instead of "begin" and "end". For example, this is a block:

        [X:= 12;   Y:= 5]
