Navigating file access and existence checks in RPGLE, especially with external systems, can be quite complex.
That's why I'm excited to introduce ifs_Obj_Exists—a function designed to simplify this process.
This powerful function allows you to:
- Check File Existence: Verify if a file exists in the IFS folder.
- Determine Access Modes: Assess various access permissions such as read, write, or execute.
With ifs_Obj_Exists, you can streamline your RPGLE code, enhance efficiency, and make file
management tasks a breeze. It’s an essential tool for any RPGLE developer dealing with file operations. 🚀💻

How to Use the JSIFSOBJEX Service Program
1. Source Code Placement
Ensure the following setup:
- The source code QPROTOSRC/JSIFSOBJEX must be placed in the QPROTOSRC source member.
- The source code QRPGLESRC/JSIFSOBJEX must be placed in the QRPGLESRC source member.
- Both source members should reside within the same library.
2. Purpose
The QPROTOSRC/JSIFSOBJEX member is used within QRPGLESRC to copy the necessary
declarations and parameters for the application to function as a service program. This is achieved by binding
the /copy directive during the compilation process.
Additionally, the QPROTOSRC/JSIFSOBJEX source code is utilized by RPG applications that require
this service program.
3. Compilation Instructions
Step 1: Create the Module
CRTRPGMOD MODULE(*CURLIB/JSIFSOBJEX) SRCFILE(*CURLIB/QRPGLESRC) SRCMBR(JSIFSOBJEX) DBGVIEW(*SOURCE) REPLACE(*YES)
Step 2: Create the Service Program
CRTSRVPGM SRVPGM(*CURLIB/JSIFSOBJEX) EXPORT(*ALL) ACTGRP(*CALLER)
Note: The *CURLIB is used as the default library in this example. You may specify any
library where you want the objects to be stored.
4. Binding Directory
Once the service program is created, it should be added to a binding directory. For example, I use JASTOOL as my binding directory. You can use any binding directory that suits your needs.
ADDBNDDIRE BNDDIR(*CURLIB/JASTOOL) OBJ((JSIFSOBJEX))
Use Case
To call the Obj_Exists see below example:
