+NAME
+ switch
+
+SYNTAX
+ switch (expr) block
+
+DESCRIPTION
+ Branch to the case label in statement that matches expr.
+ If no matching case label is found (by value or by type),
+ branch to the default label in statement.
+
+ A case label has the form
+
+ case expr_n :
+
+ where expr_n must be constant, or the form
+
+ case expr_n1 .. expr_n2 :
+
+ where expr_n1 and expr_n2 must be numeric constants and
+ expr_n1 < expr_n2.
+
+ Either all case labels have to be strings or all have to be
+ numeric. Only 0 is special: it is allowed in a switch
+ statement where all other labels are strings.
+
+ A default label has the form
+
+ default :
+
+ The default label defaults to the end of statement if not
+ given explicitly.
+
+ Whenever a 'break' statement is executed inside 'statement' a
+ branch to the end of the switch statement is performed.
+
+EXAMPLE
+ Typical usage:
+
+ switch(random(100)) {
+ case 0 .. 22 : write("Nothing happens"); break;
+ case 23 .. 27 :
+ write("You are surrounded by a golden glow");
+ this_player()->heal_self(random(3));
+ break;
+ case 28 .. 32 :
+ write("The water was poisoned!\n");
+ this_player()->add_exp(this_player()->hit_player(random(4)));
+ break;
+ case 33 : write("You hear a voice whispering: "+random_hint());
+ /* fall through */
+ case 34 :
+ write("While you didn't pay attention, a water demon "
+ "snatches a coin out of your purse!\n");
+ this_player()->add_money(-1);
+ break;
+ default : write "You hear some strange noises\n"; break;
+ case 42 : return;
+ case 99 : write("It tastes good.\n";
+ }
+
+NOTE
+ In C, the grammar for switch() is
+
+ switch (expr) statement
+
+ allowing constructs like
+
+ switch (expr)
+ while (expr2)
+ {
+ case 1: ...
+ case 2: ...
+ }
+
+ In LPC a switch has to be followed by a block that contains the
+ case labels directly. In contrast to C the group of statements
+ following a case label have their own lexical scope so that
+ variable declarations may not cross case labels.
+
+HISTORY
+ LDMud 3.2.10 constrained the grammar to require a block for the
+ switch() body, not just a statement. This differs from the C
+ syntax, but was necessary as the compiler didn't handle
+ the statement case correctly.
+ LDMud 3.3 allowed to pass values of the wrong type to switch(), the
+ driver would in that case use the default case. Before, values of
+ the wrong type caused a runtime error.
+ LDMud 3.3.718 disallowed case labels in inner blocks and variable
+ declarations that cross case labels.
