| Syntax |
A beginStatement is:
| | begin |
| | | statementsAndDeclarations |
| | end |
|
| Description |
A begin statement limits the scope of declarations made within it to the confines of the begin/end block. In Turing, begin is rarely used, because declarations can appear wherever statements can appear, and because every structured statement such as if ends with an explicit end.

| Example |
begin
var bigArray : array 1 .. 2000 of real
… bigArray will exist only inside this begin statement…
end
|
| Details |
In Pascal programs, begin statements are quite common because they are required for grouping two or more statements, for example, to group the statements that follow then. This is not necessary in Turing as where ever you can write a single statement, you can also write several statements.
