Some Error Processing routine must be included in any application program and it is useful to use the same approach in all programs.

This Utility provides a standard solution which can be used as a standard framework in the applications.

The Utility tries to achieve following objectives:

• Obtain as much information as possible about the error condition. For this purpose it has been decided to always dump the failing program.
• Provide the user with some information and directions about the actions needed to continue and avoid them to receive puzzling system messages.
• Trap all messages so that they appear on the job log.

The Utility includes:

• The GRCFAIL CL program which displays an information screen for interactive programs and processes the errors of both interactive and batch programs
• The Display file for the previous program
• the MSGCLR CL program used to clear a message queue
• the MSGSND CL program used to send messages to a message queue

This utility has the purpose to collect and produce Cross Reference information about an application on an IBM iSeries (AS/400) system.

Often applications have a large number of files and programs and it can be quite time consuming to answer question such as:

• What are the attributes of a file ? (e.g. description, type, access path)
• Where is a file used ?
• What are the relationships between files ?
• Which fields exist in a file ?
• What are the keys of a file?
• Which programs are called from a given program ?
• Which files are used from a program ?

These and many more similar questions can be answered by using AS/400 commands such as DSPFD, DSPFFD, DSPPGMREF etc or by searching in the program sources., but it is surely a time consuming activity that can be often avoided by inquiring a cross reference database.

This utility provides the programs to easily create the application cross reference database and to answer questions such as those detailed above.

The utility consists of two main parts as follows:

• Management of the cross reference environments. This is achieved by calling the program XENVM1 which allows to create cross reference environments for new applications, to inquiry their definition and to delete them.
• Inquiries on a selected environment. This is achieved by calling the program XREF01 that allows to select the type of inquiry and calls the appropriate programs to answer it.

The programs have been written in Cobol with embedded SQL.
