Rational Developer for IBM i 9.6 Fixpack 7 is now available! The 220.127.116.11 fixpack contains some nice little enhancements and fixes!
One feature really caught my eye- The New extract procedure refactoring feature, used to convert business rules into reusable procedures in RPG sounds a bit saucy.
How does ‘Refactor Extract Procedure‘ work?
We select a block of code in a source member and:
right-click -> Refactor -> Extract Procedure
This grabs the code, creates a procedure, letting us change the procedure name to whatever we want. A great tool to convert those old blocks of code (or subroutines) into sub-procedures.
This is something I’ve wanted for a long time.

How can I install the latest fixpack?
Follow the same steps I waffled about in a previous blog – How to update RDI
After the upgrade finished, I launched RDi and saw a new screen. The INSTALL MIGRATION WIZARD:
This wizard imports and reinstalls previously installed plug-ins. It is triggered because we are launching eclipse for the first time or your IBM Rational Developer for i has been updated.
Press NEXT and it wobbled around for a few seconds:
Anyhoo, lets cancel this and dive into this new 126.96.36.199 version:
First Look: New Extract Procedure Refactoring feature
Let take some very smelly old RPG400 column based code (in this case the standard IBM i PROOF RPG code snippet) and convert something to a sub-procedure.
Why? Because there is nothing like giving this new “Extract Procedure Refactoring” function a good solid complicated bit of legacy code to test it with:
H DFTNAME(PROOF) FQSYSPRT O F 132 PRINTER D ARRAY S 8 DIM(3) D CTDATA PERRCD(1) D INSTALL C CONST('INSTALLATION') D DS DS D OK 1 8 INZ('VERIFIED') C EVAL OK = 'FAILED' C MOVE ARRAY(2) ARRAY(3) C RESET OK C SETON LR OQSYSPRT T LR 1 1 O INSTALL 21 O 24 'OF' O 28 'THE' O 36 'ILE RPG' O 45 'COMPILER' O + 1 'IS' O OK + 1 ** COMPILE TIME ARRAY
And just for giggles lets change the main code into a subprocedure called mainline.
Open this code in RDi:
Select the code block that we want to convert into a sub-procedure:
Then we just right click and select > REFACTOR > EXTRACT PROCEDURE
Very nicely, this little extract gives us various options to control how our new procedure is going to look:
For this first run, lets leave it at default and see what it does:
But isn’t that old fashioned RPG400 code ugly!
So, by sheer coincidence, an old mate of mine emailed me some code yesterday asking me to cast my critical modernisation eye over it and make some recommendations.
So, lets run that code through some code modernisation and then use this refactor process to convert all the subroutines to sub-procedures.
Yes, Yes, I know that this idea is overkill, nonsensical and totally unnecessary, but totally fun too 🙂Me. In Nerd mode.
Second Look: New Extract Procedure Refactoring feature with modern RPGLE
OK, this blog entry is getting so long and excitedly waffley its time to break this second RPGLE example into another blog entry:
