An imperative statement either specifies an unconditional action to be taken by the program or is a conditional statement terminated by its explicit scope terminator (see Delimited scope statements). A series of imperative statements can be specified wherever an imperative statement is allowed. A conditional statement that is terminated by its explicit scope terminator is also classified as an imperative statement (see Delimited scope statements). The following lists contain the COBOL imperative statements.
