Ada Programming/Keywords/begin

The begin keyword in Ada is almost synonymous with the { in C/C++/Java. In the paradigm of structured programming languages, a keyword or symbol is often needed to delimit the beginning of the body from the element (i.e. if, elsif, for loop, while loop) to which it pertains.

For the case of subprograms, packages, tasks and blocks this word is begin.

For example

procedure Some_Procedure is
begin
    Do_Something;
    Do_Something_Else;
end Some_Procedure;

The begin keyword is always closed with the end keyword. The opposite is not true in Ada.
