Example of Subprocedure *PSSR Subroutine with GOTO *-----------------------------------------------------------------* * Start of subprocedure definition *-----------------------------------------------------------------* P SubProc B D SubProc PI 5P 0 ... *-----------------------------------------------------------------* * Body of code goes here including Since a *PSSR routine will be the same in every program, why not code it in its own member and include it in any program using a /COPY directive. Check out the Blog Archive Popular Posts ... For example, a calling program could be checking for CPE3025, and handle it separately than CPE3401.

If the exception is a function check, then an inquiry message will be displayed. File error routines can be given any name but need to be associated with the file. For this reason, you should specify special values such as *ALL after the specific status codes. The ENDSR operation must be the last specification for the file error subroutine.

After it finds the file, its possible that the program creating the file may still be writing data to it so it may be in use causing the copy object command We will also check at the end of the program to make * * sure we didn't miss any errors. * *-----------------------------------------------------------------* D pConHdlr S * PROCPTR D INZ(%paddr('RPGHDLR')) *-----------------------------------------------------------------* * Some points to note.

For a CPF exception, this field contains a CPF message number. The ENDSR operation must be the last specification for the program error subroutine. Exception Handling within a Main Procedure When an exception occurs within a main procedure ILE RPG does the following: If an error indicator is present on the calculation specification and the Similarly, a *PSSR in a subprocedure will only handle the errors in that subprocedure. 4.      Default exception handler           Priority of Exception handling   If any exception occurs then as

To monitor for these errors, you must check for the *STATUS value and not for the corresponding major/minor return code value. File Exception/Error Subroutine (INFSR) To identify the user-written Getting a human-readable error message In addition to the named constants for each error number, it's useful to have a "human-readable" error message that corresponds to each error number. The IF, DO, and SELECT groups can be nested within monitor groups. §  If a monitor group is nested within another monitor group, the innermost group is considered first when an Figure 124.

If the subroutine was called by the EXSR operation and factor 2 of the ENDSR operation is blank, control returns to the next sequential instruction following the EXSR operation. Depending on the response to the inquiry message, PRC2 may be terminated and the exception percolated to PRC1 (response is 'C') or processing may continue in PRC2 (response is 'G'). A file error subroutine (INFSR) receives control if the exception occurs: On an implicit (primary or secondary) file operation On an explicit file operation that does not have an indicator specified Information regarding the program exception/error is made available through a program status data structure that is specified with an S in position 23 of the data structure statement on the definition

Information regarding the file exception/error is made available through a file information data structure that is specified with the INFDS keyword on the file description specification. C MOVE '0' SW C ENDSR Note:It may not be possible to continue processing the file after an I/O error has occurred. Overwriting the file feedback section of the INFDS may cause unexpected results in subsequent error handling and is not recommended. The "void" signifies that there are no parameters.

Embedded SQL assumes you are using SQLCODE or SQLSTATE to check whether or not each statement worked. Blanks are only valid at runtime. 50-76 Blank.

This field applies to the century part of the date in positions 270 to 275. Any other unexpected error will cause a runtime error * * message. * *=================================================================* *-----------------------------------------------------------------* * Define the files: * * 1) PRDMAS - Product master file * * 2) TRANSACT Make it as complex or as easy as it needs to be. Input Record Routine *TOTC.

SearchDataCenter In VMware vs. However, depending on how the *PSSR is written, loops may occur if an exception occurs while processing the *PSSR. To add a *PSSR error subroutine to your program, you do the following steps: Optionally identify the program status data structure (PSDS) by specifying an S in position 23 of the Stay ahead of what's going on in your system so it won't spin out of control.

Optionally identify the file information data structure on a File Description specification using the keyword INFDS. Hyper-converged infrastructure watchers mull losses and layoffs So what if many top vendors in the hyper-converged infrastructure market aren't profitable? Include an INFSR(*PSSR) keyword for every file. This scenario has the following assumptions: There are two programs, PGM1 and PGM2 which run in the same activation group.

This subroutine calls the CEEHDLR API, passing it the procedure pointer to RPGHDLR. Just as the program has an error handling subroutine in *PSSR, each file that you define on an F spec can also have its own error handling subroutine, identified by the If they are specified as named constants, the constants must be character and must contain only the return point with no leading blanks. Note:In this book the term 'exception handling' is used to refer to both exception handling and error handling.

This was done to detect any physical connectivity issues with the printer.2) After having answered this, they confirmed that the printer and the laptop were functioning correctly.3) They then, asked me Just as I finished writing this article I came across this interesting thread on the very same topic. Note that the *PSSR in a subprocedure is local to that subprocedure.

You can register more than one ILE condition handler. See User Date Special Words for a description of UDATE. C ELSE C MOVE '1' SW C : C : C : C ENDIF C* End error processing. Use information in the Information Center to determine which fields you wish to include in the INFDS.

Call Enabler. See subfield DB_RRN in DBFBK data structure in example below Figure 29. The length of the INFDS when device specific feedback information is required, depends on two factors: the device type of the file, and on whether DISK files are keyed or not. Conclusion All you have to do is this: Write a standard *PSSR subroutine and place it in a copy member.

If a subprocedure is called recursively, only the invocation that calls CEEHDLR is affected by it. The contents of the device specific input/output feedback area of the file are copied by RPG to the device specific feedback section of the INFDS: If a POST for any file You can use the Program Status Subroutine (PSSR) to provide a better postmortem diagnostic for such cases, but even then the results are virtually always the same: Your program still crashes.
