Case statement
Use the case statement to pass control to a specific program branch, based on a
certain condition. The
case statement consists of a selector expression (a condition)
and a list of possible values. The syntax of the case statement is:
case selector of
value_1 : statement_1
...
value_n : statement_n
[else default_statement]
end;
selector is an expression which should evaluate as integral value. values can be
literals, constants, or expressions, and statements can be any statements.
The else clause is optional. If using the else branch, note that there should never
be a semicolon before the keyword
else.
First, the selector expression (condition) is evaluated. Afterwards the case state-
ment compares it against all available values. If the match is found, the
statement
following the match evaluates, and the case statement terminates. In case there are
multiple matches, the first matching statement will be executed. If none of values
matches selector, then
default_statement in the else clause (if there is some) is
executed.
Here’s a simple example of the case statement:
case operator of
'*' : result := n1 * n2;
'/' : result := n1 / n2;
'+' : result := n1 + n2;
'-' : result := n1 - n2
else result := 0;
end;
Also, you can group values together for a match. Simply separate the items by commas:
case reg of
0: opmode := 0;
1,2,3,4: opmode := 1;
5,6,7: opmode := 2;
end;
