Ada Programming/Keywords/begin
Appearance
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_Procedureis
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.
