Session or Device Error Occured

Session or Device Error Occured

There are few scenarios where Subfile would crash with 'Session or Device Error Occured'.

Below mentioned are the few scenarios when this issue would occur.


  • Incorrect Record Number in SFLRCDNBR

Variable associated with Keyword SFLRCDNBR (RRN) should be greater than Zero


  • Displaying Empty Subfile

No Records to display and still SFLDSP indicator is ON.


  • Attempting to write more than 9999 records into Load All Subfile

Maximum number of records allowed on Load All Subfile is 9999. Attempting to write more than 999 would result in Program crash.

What is the importance of User Open (USROPN) in RPGLE - IBM i

User Open (USROPN) USROPN (User Open) in RPGLE provides the flexibility for the programmer to open a file at a specific point in the program execution. In this post, let's explore what is the use of a USROPN and what is the importance of USROPN and how to use it with a simple example. What is the use of USROPN? By default, any file in the RPGLE (defined in F-Spec) opens as soon as the program execution is started and file is closed at the end of the program (by setting LR indicator ON). A simple RPGLE program looks something like this on a high level with out the use of a USROPN.  1 2 3 4 5 6 7 8 9 10 11 **Free                                  Dcl-F TestFile;                            ...

What is Deep Learning? Beyond the Basics of AI

What is Deep Learning? Beyond the Basics of AI AI’s everywhere—unlocking your phone, suggesting playlists, even driving cars. But how does it get *so* smart? Enter deep learning—a game-changer in artificial intelligence. Welcome to Decoding Complexities , where we unravel tech’s toughest puzzles. If you read “What Are Neural Networks?” you’ve brushed against this. Now, we’re going deeper. In this post, we’ll decode what deep learning is, how it powers AI’s wildest feats, and why it’s more than just buzz. From self-driving Teslas to ChatGPT, it’s the engine behind the magic. Let’s break it down—ready? Deep Learning: The Basics Deep learning (DL) is a subset of machine learning—itself a chunk of AI. Remember neural networks from my last post? DL cranks them up—think neural networks on steroids. It’s all about *deep* neural networks—piles of layers that dig into data to find patterns no human could spot. Here’s the gist: More Layers: Regula...

What is Artificial Intelligence?

Artificial Intelligence Artificial Intelligence (In short, AI) is a highly sought-after skill in the Tech Industry today. In this post, let's try to understand " What is Artificial Intelligence? ". Before we dive in, let's first understand "What is Intelligence?" As humans, we think and act. This involves understanding our environment, predicting outcomes, and behaving accordingly. Similarly, AI focuses on building machines that can understand, predict, and act/respond effectively and safely. AI isn't exclusive to any specific industry. Its applications spread across different industries, including playing chess, proving mathematical theorems, driving cars, writing poetry, composing music, generating videos, diagnosing diseases, and much more. The field is continually evolving. Initially, AI was often defined in relation to matching ' Human performance '. However, AI has surpassed human capabilities in several areas and ...
