How do we use these templates? To include a template in your source, key the template name and press the ctrl-Space key combination. If you need to create your own templates, use the New… button to create your own. To see all the code templates already provided for us, navigate to Windows → Preferences then navigate as shown in the figure below. The advantage of using free-form coding is that the templates can be used throughout your code. Code Templates and Context AssistĪs their names suggest, these are used to place template code in our C specs. In the example below, we input the package and class details, then the Java method to call.Īll the procedures and definitions, along with the method call are coded for us. As with the previous two wizards, select Source → New → Java Method Call … This will start the Java wizard. The wizards can help us enormously in creating the entire necessary source. The features to allow us to call Java objects were introduced in V5R1 of RPG. Once again, the source is generated and inserted where required in our source. Select the D-Specification type of Program described data structure. In the figure below, we can see all the options that are available.įor this example, we are going to generate a data structure to hold our supplier details.

As with the previous wizard, select Source → New → D-Specification… This will start the wizard. With the D-Specification wizard, as you would imagine, we have lots of options for all the various layouts. The procedure wizard is a great way to standardise our coding.

Our prototype and procedure is shown in the figure below.

Once all details have been input, the code is generated and placed in the correct location within our source. To start the wizard, take Source → New → Procedure.Īs we are going to show you free-form code, ensure you tick the Generate free-form D-spec and P-spec code.Įnter all the details you need for the sub-procedure, including any parameters and return values. The procedure wizard is very useful for remembering what piece of code to place where – where the PI coding goes, where PR coding goes and so on. The first wizard I am going to show you is how easy it is to code a sub-procedure. Rational Developer is great for introducing us to this latest syntax. So what do we have to help us with programming if we are using Rational Developer? By the way, the coding examples shown here are all of the latest free-format type. And, having been a programmer for over 32 years, I am all for anything that saves me coding.įor example, if a database uses auto increments on account numbers, it saves me lines of coding. Gone are the days when we had a DPM (data processing manager) looking over our shoulders to ensure that we were thrashing out code (we didn’t have fancy job titles back then, either). I’m going to run through some of the shortcuts/wizards we can employ with RPG using Rational Developer for i (RDi).
