Functional Enhancements

  • Unmap for IBM FlashSystems configurations


Application Development 

Rational Development Studio for i 

The RPG language continues to move forward as a Modern Business Language.  RPG ILE has been enhanced to support the parsing of multiple states types (like JSON) with the new DATA-INTO function. 

The new function incorporate the ideas of XML-INTO and RPG Open Access. DATA-INTO imports data from a data document into a data structure. It is capable of handling many types of data documents including JSON, Property files, CSV files, and more.  A 'handler' program is leveraged to actually provide the parsing support. Several sample parses are being shipped with DATA-INTO for parsing JSON documents as well as Property Files. This new support give the IBM i development community an easy way to add support for new data types or even their own private data types. Full details can be found at RPG Cafe once the PTFs have been made available. 

Great article on this can be found at IBM Systems Mag.


IBM i Integrated Web Services Server


Authenticated User - The IWS support has been enhanced to now support the usage of the Authenticated User profile across the connection. This means that the backend ILE program can now be dynamically set to use the authenticated user profile vs using a hard coded value that was required to be set during the setup process 

Web Services Re-Deploy - Additionally the IWS support has been improved to now allow services to be re-deployed vs having to completely remove and then re-install. 

VAR CHar Support -  PCML version 7 now has support the type variable length fields (varchar)

 - User can now define a field of type VarChar

 - Eliminates the need for an extra field to detect field lengths 

 Details can be found in the Integrated Web Services Server Administration and Programming Guide and the Technology Updates web page, which may be found on the Integrated Web Services Product page:

IBM i Integrated Web Services Client

The ability to call Web based APIs easily from your ILE program continues to be improved. 

 Access SOAP Faults from RPG stub PGMs. - Determine what error occurred during the SOAP services call

SOAP infrastructure provides a documented error return structure
  • This will now be accessible from your RPG program
  • Improved error response

Details can be found in the Web Services Client for ILE Programming Guide and the Technology Updates web page, which may be found on the Integrated Web Services Product page:


Compile CL from IFS Source

When looking to leverage new development tools for things like source control management, one of the key requirements is that the source be accessible from IFS. The RPG and COBOL compliers have supported this for a while now.  The CL language is now stepping up to provide the initial level of support.  The following CL commands have been enhanced:



Both the SRCSTMF and INCDIR parameters have been added to allow IFS source

 SRCSTMF parameter has been added to the INCLUDE command so users can embed another source file stored in IFS stream files. 

 This is a key step for being able to now manage your CL source using a source control tool like Git. 


ARCAD Converter for i -   5733-AC1

New updates to provide the best possible experience when converting your fixed form RPG to Fully Free-Format RPG. Updates include better handling for truncation issues, including warning or the ability to auto fix/update. The latest updates will be available in ESS in March.  Details can be found on ARCAD Converter for i.


ARCAD Observer for i -  5733 A01

New enhancements and updates to the 5733-A01 product targeted to help application developers better understand their applications and make the correct decisions as they navigate the modernization journey. The latest updates will be available in ESS in March.  Details can be found on ARCAD Observer for i.
