PROCESS Usage

The PROCESS statement is used in conjunction with Entire System Server and Natural Messaging.

Entire System Server allows you to use various operating system facilities such as reading and writing files, VTOC and catalog management, JES queues, etc. See the section Getting Started in the Entire System Server User's Guide for further information on the PROCESS statement and its individual clauses.

Natural Messaging is a Natural add-on for z/OS that supports communication with IBM MQ. It allows you to easily access message queues using the PROCESS and FIND statements. For further information, see Database Management System Interfaces > Natural Messaging in the Natural for z/OS documentation.

PROCESS Restriction

This statement is only available with Entire System Server and Natural Messaging.

When the ERROR-CODE or ERROR-TEXT field is included in the view as part of local data, the default Natural system error messages are suppressed. Instead:

• ERROR-CODE will contain the error code, and

• ERROR-TEXT will contain a descriptive message explaining the exact cause of the error.

This allows the calling Natural program to handle errors programmatically, without triggering a system-level abend or Natural error message.

PROCESS Syntax Description

Operand Definition Table:

Operand	Possible Structure					Possible Formats													Referencing Permitted	Dynamic Definition
operand1	C	S				A		N	P			B							yes	no
operand2	C	S				A	U	N	P			B							yes	no
operand3		S				A		N	P			B							yes	no

Syntax Element Description:

Syntax Element	Description
view-name	View Name: Name of the view used.
USING	USING Clause: The USING clause is used to pass parameters. This is done by assigning a value (operand2) to a field (operand1) in a view. Note Multiple specifications of operand1=operand2 must be separated either by the input delimiter character (as specified with the session parameter ID) or by a comma.
GIVING	GIVING Clause: The GIVING clause is used to specify the fields (operand3) for which values are to be returned. Each field must be defined in a view.
