Often, while testing application programs, you need to run a program that uses logical files. But, to avoid the problem of inadvertently updating production (live) files, you need to play it safe: You must first make a copy of the physical file and its related logical files in another library. Then, you must place that library high in the library list so the system finds it before it finds the library with the original, production, files.
However, you are faced with the problem of finding which logical files are attached to the physical file and then running all the appropriate commands to make the duplicates. So, I created a utility that will copy a physical file and all of the logicals that go along with it. Thus, you have the Copy All Logical Files (CPYALLLF) command (see Figure 1).
CPYALLLF asks for the qualified name of the physical file and the name of the target library. It then does a little editing to make sure that you actually enter valid libraries, verifying that the "from" and "to" libraries are not the same and that the physical file actually exists in the original library (if it exists in the target library, it will ask you if you want to proceed).
Then, CPYALLLF performs a Display Database Relations (DSPDBR) command to find all the logical files attached to the physical file. After that, it calls a program to delete all the logical files, if any exist, and then the physical file in the target library. Once this is done, the program does a Copy File (CPYF) from the original library to the target library (see Figures 2 and 3). Then, it calls the same program used to delete the logical files but with a different parameter to add the logical (see Figure 4). That’s it; now, you have your physical file and all of its logicals where you need them!
CPYALLLF prints an exception report for any of the following reasons:
• The file was not created because it is a join logical.
• The file was not created because you do not have authority to that object in the library in which it resides.
• The file was not created because it was not found in the original library.
• The file was created in the target library.
You can modify this utility by cloning the part that deletes the logical files and then the physical file for a quick delete after you no longer need the files.
I have found the CPYALLLF command to be a useful and efficient utility. Currently, I am on a Y2K team, and the testing sometimes produces unpredictable results. Glad it was done in my library, which didn’t affect the whole system.

MarkMagic is the only document design and print solution that combines report writing, WYSIWYG label and forms design, and conditional printing in one integrated product. Make sure your data survives when catastrophe hits. Request your trial now! Request Now.
Forms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.
Disaster protection is vital to every business. Yet, it often consists of patched together procedures that are prone to error. From automatic backups to data encryption to media management, Robot automates the routine (yet often complex) tasks of iSeries backup and recovery, saving you time and money and making the process safer and more reliable. Automate your backups with the Robot Backup and Recovery Solution. Key features include:
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
IT managers hoping to find new IBM i talent are discovering that the pool of experienced RPG programmers and operators or administrators with intimate knowledge of the operating system and the applications that run on it is small. This begs the question: How will you manage the platform that supports such a big part of your business? This guide offers strategies and software suggestions to help you plan IT staffing and resources and smooth the transition after your AS/400 talent retires. Read on to learn:
