INITIALIZE(初期化)文
The INITIALIZE statement provides the ability to set selected data items to specified values.
INSPECT(文字列検査)文
The INSPECT statement provides the ability to tally (Format 1), replace (Format 2), tally and replace (Format 3) , convert (Format 4) and tally trailing (Format 5).
INVOKE(メソッド呼び出し)文
The INVOKE statement causes a method to be invoked.
MERGE（併合）文
The MERGE statement combines two or more identically sequenced files on a set of specified keys, and during the process makes records available, in merged order, to an output procedure or to an output file.
MOVE（転記）文
The MOVE statement transfers data, in accordance with the rules of editing, to one or more data areas.
MULTIPLY（乗算）文
The MULTIPLY statement causes numeric data items to be multiplied and sets the values of data items equal to the results.
NEXT SENTENCE（次の完結文）文
The NEXT SENTENCE statement transfers control to the next COBOL sentence, that is, following the next period. It does not transfer control to the logically next COBOL verb as occurs with the CONTINUE verb.
NOTE（注記）文
The NOTE statement introduces a sentence or paragraph that will be treated as comments.
ON（回数間隔）文
The ON statement allows selective execution of procedural statements on a periodic basis.
OPEN（開く）文
The OPEN statement initiates the processing of files. It also performs checking and/or writing of labels and other input-output operations.
PERFORM(実行)文
The PERFORM statement is used to transfer control explicitly to one or more procedures and to return control implicitly whenever execution of the specified procedure is complete.
READ(読み込み)文
The RELEASE statement transfers records to the initial phase of a SORT operation.
RESET Collection 文
Deletes all the elements from the list or dictionary.
RELEASE(引き渡し)文
The RETURN statement obtains either sorted records from the final phase of a SORT operation or merged records during a MERGE operation.
RETURN(引き取り)文

SET(設定)文
The SET statement is used to alter the status of external switches.
SORT(整列)文
The SORT statement creates a sort file by executing input procedures or by transferring records from another file, sorts the records in the sort file on a set of specified keys, and in the final phase of the sort operation, makes available each record from the sort file, in sorted order to some output procedures or to an output file.
START(位置決め)文
The START statement provides a basis for logical positioning within a relative or indexed file for subsequent retrieval of records. This statement is not available for files with sequential organization.
