This morning my nerdish IBM-i Chum Toby, pinged me a whatsapp challenge to write a little RPG code snippet to “extract invoice numbers” from a random string of data. So…. if you had a string ‘INV#10563592 DATED 12/17/19 SO#286045 NOT GOING’ and you knew that this is a shitty text file way of referencing an […]

Use the Retrieve Job Attribute (RTVJOBA) command to snaffle the job’s run type from the attributes. Seems pretty obvious right? One little niggle was that the RTVJOBA passes back a char(1) value for the jobtype where ‘0’ means batch and ‘1’ means interactive. But, I want to be able to neatly compare a logical value […]

Lets start with a reasonably mixed RPGLE code example which is older style column based RPG400 for its variable definitions but then uplifts to RPGLE /FREE for its body code: Step1 – Run code through the Projex4i Code Moderniser. The Upgrade RPG Source command (UPGRPGSRC) will clean our code, converting it to fully /FREEFORMAT ILE […]

Rational Developer for IBM i 9.6 Fixpack 7 is now available! The 9.6.0.7 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 […]

I was updating a little RPG utility this morning to add some more detail to a spreadsheet it generated. Adding the Library Description will help the non-propeller heads who read this stuff. This is super easy to do with a single line of SQL added to your RPG program. What is this spreadsheet you are […]

Googling, Binging and Duck Duck Going, frantically searching for help with RDi? Back in October 2019, IBM announced they were killing the Developerworks website: “As part of the overall IBM effort […]

I was discussing the benefits of RDi with a colleague this morning (I’m a bit of a Rational Developer fanboy) because he is trying to justify the huge annual cost of the tool with The Management: nearly $1000 per year per person! A price tag that is #bloodypreposterous. But, I will rant about that in […]

So – today I was talking to colleague who wanted to make a database change to a big old file. This meant changing one of the fields from 7 numeric to 12 alpha. Sounds simple right? Oh if only life were that simple… Now add the complexity that you have to do this change in […]
