Remember that you need my CLANA00F file to compile the following program. So, first of all look at this post and compile and populate these files to use this example.

Now execute:

CALL A01ARPCL


Fill the CUSTOMER CODE with a value and type ENTER...


Type F6=EXIT or F6=GO...




Don't forget to set the screen to 132 columns!



I appreciate all the comments made on this blog.

    I don’t really like it when I see code with “Dow (1=1)”. Make the code have a real meaning. Like “Dow P1Exit <> ‘1’”

      I don't like leave in Loop.
      I don't like association between CFxx and general indicators. Better using *ink_ (dow 1=1 become dow not *inkc).
      With flat screen, not need a plus format for bottom.

      Thank you for your continued input; your insights are incredibly valuable. I appreciate your specific suggestions regarding leaving loops, the use of *ink_ for indicators, and the elimination of the plus format for the bottom with flat screens. Your guidance will certainly help enhance the program.

      I'm grateful for your help in making the code more efficient and readable.

      As soon as I can, I'll make the adjustments to the code.

    Thank you for sharing your thoughts, and I genuinely appreciate your feedback. It's always valuable to receive input from peers like you. I'll take your advice to heart and strive to make the code more meaningful in the future. If you or any of my LinkedIn friends have additional suggestions, please don't hesitate to share them. Constructive feedback helps us all grow and improve. Thanks again!

(IBM i fans only) Efficient WRKSPLF with WSF - How to Search string into spooled files, Sort, and Generate PDFs on IBMi

Searching Spooled Files Made Easy: A Unique Solution Managing spooled files efficiently is crucial for users dealing with numerous rows of print data. IBM's WRKSPLF command provides a standard way to interact with spooled files, but it lacks certain features that can significantly enhance user experience. In this article, we'll delve into a powerful functionality that IBM doesn't offer — the ability to search among spooled file lists. Our goal is to highlight the advantages of this capability and introduce a practical solution. The Limitations of Standard WRKSPLF While the WRKSPLF command is a handy tool for working with spooled files, it falls short in certain aspects. One prominent limitation is the inability to search efficiently through the list of spooled file rows. Users often find it challenging to quickly locate specific files based on criteria like creation date, status, or content. Introducing a Unique Solution: WSF (WorkSpooledFiles) To address the limitations of...

(IBM i fans only) Detecting and Handling Non-Printable Characters in DB2 SQL Using LOCATE() and REPLACE() Functions

By -
Image
When working with DB2 SQL on the IBMi platform, one of the challenges we might encounter is dealing with non-printable characters in our data. These are characters that don't have a direct representation on a standard keyboard and can cause display programs to crash if not handled properly. For this example, we'll be working with the CLANA00F file, which contains customer data. You can find details on how to create this file on my blog post here . Non-printable characters can sneak into our records for various reasons, and to prevent issues, we can run an SQL query that uses the LOCATE() function. This function returns the position of the first occurrence of a substring within a string, allowing us to detect these problematic characters. Suppose we have a customer name with a non-printable character, specifically the EBCDIC '0D' character, which corresponds to the "Carriage Return" (CR) control character in ASCII. To find this character in our records, we can ...

(IBM i fans only) How to Sniff User Access

If you need to monitor user access on your IBM i system, you can use SQL to query the history log. Note: At the end of this post, you'll find a request directly addressed to you, the readers. Here’s a simple example of how you can do this: SELECT MESSAGE_ID,        MESSAGE_TIMESTAMP,        FROM_USER,        MESSAGE_TEXT     FROM TABLE (             QSYS2.HISTORY_LOG_INFO()         )     WHERE message_id IN ('CPF1164', 'CPF1124')           AND FROM_USER IN ('QSECOFR', 'QSYS', 'QSYSOPR')     ORDER BY MESSAGE_TIMESTAMP In this query: - QSYS2.HISTORY_LOG_INFO(): This function retrieves information from the history log. -  message_id IN ('CPF1164', 'CPF1124') : Filters the results to include only specific message IDs, which indicate sign-on and sign-off events. - FROM_USER in ('QSECOFR', 'QSYS', 'QSYSOPR'): Filters the resu...
