About Proxy Programs

A Proxy Program object automatically transfers control to a Profound.js module that is named the same as the Proxy Program and is located in the same modules subdirectory as the library in which the Proxy Program is located. All parameters passed to the Proxy Program are automatically passed along to the Profound.js module. Parameters can be passed by reference or by value. Proxy Programs typically replace the object of a converted RPG program.


  • Allows Node.js scripts to be called as if they were ILE programs
  • Provides the option to use standard IBM i security and object level authority on Node.js code
  • Allows you to assign an activation group to the called program
  • Maintains program dependencies after an RPG program is converted to Node.js
  • Allows for an agile, iterative, and incremental modernization process
  • Allows Node.js modules to be called from RPG or other IBM i languages using a standard CALL operation


Creating Proxy Programs

You can create a Proxy Program object by using the PJSCRTPRXY command located within your Profound.js installation library. The command takes the following parameters:

  • Library / Program - Specifies the name of program object to create
  • Activation group - Specifies the activation group the program is associated with when it is called; default value is *NEW
  • Creation command options - Specifies a parameter string, enclosed in apostrophes, that is added to CRTPGM command when the program is created
  • Path to Profound.js module - Specifies the path to the Profound.js module on the Profound.js server's file system. If *OBJ is specified, Profound.js will look for a module named the same as the proxy program, in a directory named the same as the proxy program library.

Once the object is created, you can work with it like any other program object. For example, you can use the WRKOBJ (Work with Objects) command to locate it. Or, you can use the EDTOBJAUT the EDTOBJAUT (Edit Object Authority) command to modify the program's authority settings.


Calling Proxy Programs

You can call a Proxy Program from Genie by using the standard CALL command or by selecting the option that called the original RPG program that you've now replaced with the Proxy Program. This will invoke the respective Node.js module. The Node.js script may either present an interactive user interface or just perform back-end business logic, in which case control is immediately passed back to Genie after the Node.js script finishes executing.

Before calling the Proxy Program, your library list should include libraries PROFOUNDUI and PROFOUNDJS or their equivalents if you installed Profound UI and Profound.js into non-default libraries.
