Data Types

The normal data type rules apply to variables and arrays in each common block. A type statement is not required if the initial letter rule would have the required effect, but type statements are advisable, especially if the implied-type rules are anywhere affected by IMPLICIT statements. Type statements may precede or follow the COMMON statement. Similarly the lengths of character items should be specified in a separate type statement: these cannot be specified in the COMMON statement.
