+NAME
+ block
+
+DESCRIPTION
+ A block is a special statment, that begins with '{', contains
+ a list of statements, and ends with '}'.
+
+ The block may define local variables. If for a variable no
+ initialisation is given, the variable is initialised to 0 every
+ time the block is entered. Otherwise, the initialisation
+ expression is evaluated and its result assigned to the variable
+ everytime the block is entered.
+
+ Example definitions are:
+
+ int i;
+ int j = 3;
+ int k = 3 * j, l;
+
+ Here, i and l are both initialised to 0; j is initialised
+ to 3, and k is initialised to 9 (3 * j).
+
+ Local variables defined in a block are visible only until the
+ end of the block. Definitions in an inner block hide definitions in
+ outer blocks.
+
+HISTORY
+ Up to 3.2.7 local variables were visible (from their point of
+ definition) in the whole function. That is, code like
+
+ do {
+ int res;
+
+ res = ...
+ } while (res == 5);
+ write(res);
+
+ was perfectly legal. It is no longer, as 'res' ceases to exist
+ with the closing '}' of the while().
+
+ Up to 3.5.0 you could get this old behaviour back with the
+ #pragma no_local_scopes and switch it off again with
+ #pragma local_scopes.
+
+ Since 3.5.0 it is not possible to disable the local scope behaviour.
+
+ Up to 3.2.8, local variables could not be initialised in their
+ definition.
