— Statements —

In structured mode and in reporting mode using a DEFINE DATA LOCAL statement, the following syntax applies:

`GET` [`IN`] [`FILE`] `view-name`
[`PASSWORD=operand1`]
[`CIPHER=operand2`]
	`RECORDS`	`operand3`
		*`ISN` [(`r)` ]

In reporting mode using no DEFINE DATA LOCAL statement, the following syntax applies:

The GET statement is used to read a record with a given Adabas Internal Sequence Number (ISN).

The GET statement does not cause a processing loop to be initiated.

The GET statement cannot be used for DL/I and SQL databases.
The GET statement cannot be used with Entire System Server.

Operand Definition Table:

Operand	Possible Structure				Possible Formats									Referencing Permitted	Dynamic Definition
`operand1`	C	S			A									yes	no
`operand2`	C	S				N								no	no
`operand3`	C	S		N		N	P	I		B *				yes	no
`operand4`		S	A		A	N	P	I	F	B	D	T	L	yes	yes

* Format B of operand3 may be used only with a length of less than or equal to 4.

Syntax Element Description:

Syntax Element	Description
`view-name`	View Name: In structured mode and in reporting mode using a `DEFINE DATA LOCAL` statement, the name of a view as defined either directly within a `DEFINE DATA` statement or in a separate global or local data area.
`ddm-name`	DDM Name: In reporting mode using no `DEFINE DATA LOCAL` statement, the name of the data definition module (DDM) is referenced.
`PASSWORD=operand1`	PASSWORD Clause/CIPHER Clause: These clauses are applicable only to Adabas and VSAM databases. The `PASSWORD` clause is used to provide a password when retrieving data from an Adabas file which is password protected. The `CIPHER` clause is used to provide a cipher key when retrieving data from an Adabas file which is enciphered. See the statements `FIND` and `PASSW` for further information.
`CIPHER=operand2`
`*ISN / operand3`	Internal Sequence Number: The ISN must be provided either in the form of a numeric constant or user-defined variable (`operand3`), or via the Natural system variable `ISN`. Note:* For VSAM databases: For VSAM ESDS, the RBA must be contained in a user-defined variable (numeric format) or must be specified as an integer constant. The same rules apply to VSAM RRDS with the exception that the RRN must be provided instead of the RBA.
`(r)`	Statement Reference: The notation `(r)` is used to specify the statement which contains the `FIND` or `READ` statement used to initially read the record. If `(r)` is not specified, the `GET` statement will be related to the innermost active processing loop. `(r)` may be specified as a reference statement number or as a statement label.
`operand4`	Reference to Database Fields: In reporting mode, subsequent references to database fields that have been read with a `GET` statement can contain the label or line number of the `GET` statement.
