Mch1202 Error In As400
(i.e, character being moved to numeric or numeric being moved to character or data lengths not matching), that could cause this error. But, when you can actually do a move operation and it doesn’t throw any error, and you have %char built in functions and all to covert numeric to character, why should a decimal data error come? Can anyone please help how to handle decimal data error in rpg me with this question? Thanks.

In my previous tip, I mentioned that one of the benefits of data structure I/O

is that you can avoid decimal data errors. In this tip I'm going to show you how and why that works. The code package associated with this tip contains three test programs that demonstrate the different scenarios. The first is a straightforward RPG program with no defenses. It reads a file in a loop and will encounter decimal data errors. The second is http://itknowledgeexchange.techtarget.com/itanswers/decimal-data-error-5/ intended to show the basic use of DS I/O. It still has errors but they are subtly different. The third program demonstrates how to extend the program to fully defend against such errors. See the Readme.txt file for instructions on how to install the source code on your system. One factor that adds to the difficulty of handling data decimal errors is that that they may occur on a READ or CHAIN operation, making it difficult to determine exactly http://www.itjungle.com/fhg/fhg031715-story01.html which field is in error. This happens because the system detects the error while moving the data from the buffer to the internal variable. When we use DS I/O, the entire record is moved as if it were a large character field. In other words the numeric data is not differentiated. Since numeric fields are not differentiated they can't cause errors! Let's walk through the process of running each of the three programs so that you can see the differences between them. First, here are relevant portions of program DATAERRS1. FBadData IF E DISK DoU %EOF(BadData); Read BadData; If %EOF(BadData); Leave; EndIf; records += 1; total += amount; date = %Date(numDate: *YMD); EndDo; If you run this program, you will receive an error when reading the second record. Using F1 to look at the actual details of the error reveals that it occurred on one of the compiler-generated lines associated with the READ. This is even more obvious when you run the program in debug. If you tell the program to go (option G) you will find a similar error occurs on the reading of the third record. In both cases, determining which field is in error is problematic and the only valid option is to cancel the program. Now run program DATAERRS2. FBadData IF E DISK D inputData E DS ExtName(BadData: *Input) DoU %EOF(BadData); Read BadData inputData; // Read into DS If %EO
This document provides information about finding and correcting decimal data errors. Resolving the problem It is not uncommon for programs http://www-01.ibm.com/support/docview.wss?uid=nas8N1018444 to have problems with decimal data errors when working with files that originated on mainframes, non-IBM systems, and the IBM System/36. Program-described files are normally used on these http://www.rpgpgm.com/2015/04/coping-with-data-decimal-error-when.html systems and can result in non-numeric hexadecimal values in numeric fields. It is also possible for a program on the IBM OS/400 or IBM i5/OS system to do data error this because program-described files are still available, especially for programs that have been migrated and are running in the System/36 environment. The following example takes advantage of the field descriptions in externally-described files to correct the problem. The program reads in each record and writes it out making assumptions on what the correct value should be. You decimal data error are responsible for evaluating the results of using this program. Because it is necessary to make assumptions, the results might not be what you require. However, there is a very good chance the results will be satisfactory. Always keep a back-up copy of the file until you evaluate the results and are comfortable with the end result. In the case of zoned numeric fields, hexadecimal values such as blanks, control characters, and unassigned hexadecimal values are normally converted to zeroes. When letters or special characters (for example, the ampersand) are encountered, the first hexadecimal character is converted to an F. For example, the letter A is C1 in hex, while the letter a is 81 in hex. Both are converted to F1, which is the number one. In testing, 8aA69 is converted to 81169. However, when certain values are encountered in certain positions in the field, the entire field can be converted to a zero value. For packed numeric fields, an incorrect value in any position normally causes
April 29, 2015 Coping with data decimal error when read file I am sure we have experienced running a program when it errors with "Decimal-data error occurred", RNQ0907. After analyzing the program I would find that the error is caused by bad data in a field in the input file. Yes, I will correct the bad data, but I might want to have the program continue using a default value and create a dump that can be used for analysis later. Examples of creating dumps can be found in the post: Producing a dump from programs. How can I flag the record as having an error, give the numeric field a default value, and continue processing? First let's start with our file, TESTFILE. It contains two fields, see below: The program will only error if the field containing the bad data is used. A R TESTFILER A FLD1 3P 0 A FLD2 5A I put blanks into FLD1, the numeric field, of the second record of the file: FLD1 FLD2 1 ONE TWO 3 THREE All I am going to do is to create simple RPG program to read TESTFILE and output to the display, using RPG's DSPLY operation code, the values of the two fields, see below. If you are not familiar with all free RPG line 1 denotes that TESTFILE is being for only input. 01 dcl-f TESTFILE ; 02 dow (1 = 1) ; 03 read TESTFILER ; 04 if (%eof) ; 05 leave ; 06 endif ; 07 dsply ('Record = ' + %char(FLD1) + ' ' + FLD2) ; 08 enddo ; 09 *inlr = *on ; Which when I run this program the output will be: DSPLY Record = 1 ONE Decimal-data error occurred (C G D F). I can take the option "D" to create a dump, and the program ends. If I did not need FLD1 I would just remove it from line 7, see below. Now when the program runs it does not error as FLD1 is not used. 07 dsply ('Record = ' + FLD2) ; So what approaches are there to stop the program erroring and continue? The first approach I tried was using the *PSSR subroutine. This subroutine is only executed when an error occurs, any error. It is just coded like any other subroutine, the only difference is the second parameter with the ENDSR operation code, line 14. 01 dcl-f TESTFILE ; 02 dow (1 = 1) ; 03 read TESTFILER ; 04 if (%eof) ; 05 leave ; 06 endif ; 07 dsply ('Record = ' + %char(FLD1) + ' ' + FLD2) ; 08 enddo ; 09 dsply ('End of pgm') ; 10 *inlr = *on ; 11 be
