Kimbra Koran
Download a full version of RDi with a 120 day trial license. Gain free, hands-on experience. Note that the trial is identical to the full version. The only difference is the license, so this is an alternative method to acquiring and installing the product. The full license just needs to be applied within 120 days, see How to buy RDi and Deciding what type of IBM Rational Developer for i License to purchase. For alternate install methods or information on how to deploy RDi to all developers in your shop, see How to install Rational Developer for i at the latest level on multiple developer machines.
Personally, like many other programmers these days, I do not only code in RPG and the nuances between languages can cause confusion. For example, operational codes for string handling, like substring, that are spelt different in other languages; very annoying. This is where context assist functionality is a very useful.
Context Assist uses the ctrl-Space key combination. In the figure below, it can be seen if I type %SU then the ctrl-Space combination. All the valid operational codes are displayed and you can then drill down to the operational code you need. It will show all the necessary parameters and their order.
From the moment I decided to focus my attention on IBM I sources, the only tool I want to develop with is RDI. It is in no way conceivable to continue using the SEU and I believe that the time has come to write more and more code in ** free format. This IDE integrates developer tools, such as search, edit, development, analysis, refactoring, and debugger capabilities with the widely deployed Eclipse framework, for faster and easier application development and modernization.
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
This semantic approach emphasizes the editing benefits of types. As a developeredits code, an IDE can use type information with many tasks, especially namecompletion and checking for typo-level mistakes.
A rational-programmer investigation can answer this question (to some extent).Here is how. Imagine running a gradually typed code base with a known typemismatch, that is, an untyped piece of code treating a value from the type sidein an inappropriate manner. Thus the above question is specialized to this:Which of the semantics helps discover the problem and track down its source?
In short, the rational programmer must use the runtime stack information to findthe actual source of the problem as opposed to its symptom. The astute readermight be wondering now whether the runtime stack is useful in our example or ingeneral.
Based on this analysis, we can see that these two questions are algorithmic innature. That is, we can implement a rational programmer and run it on thousandsand tens of thousands scenarios to find out whether the semantics differeffectively during debugging sessions. In other words, we can find answers tothe original pragmatics question in an automated manner.
The rational approach is to derive test cases for the called functions from thefailing test case of the calling function. Derive means to construct theinputs of the new test case from the inputs of the failing test using the shapeof the embedded function call; the rational programmer must also calculate theexpected output for these inputs. Once these derived test cases exist, therational programmer re-runs the test suite to see whether the derived tests workproperly.
The add-path function depends on one user-designed function:link. To rule out a bug in this dependency, the rational programmeronce again derives tests for the dependency (link) from the buggy testfor add-path: see figure 15. The tests add one side ofthe triangle, two, and all three, respectively. All of them pass.
In the meantime, language researchers work on enhancing compilers, lifting thelevel of debugging, and experimenting with alternative ways of profilingcode. For compilers, researchers can often show that for some collection ofwell-known benchmark an enhanced compiler performs better on many programs, butnot all. For other tools, however, they face the same problem as languagedesigners: they often cannot validate that developers would be better off withone or the other variant of the same tool.
IBM i developers have a few exciting new features to look forward to with the latest Technology Refreshes for IBM i 7.5 and 7.4, including a new release of RDi and new RPG and COBOL functions in the compilers.
IBM last month unveiled Rational Developer for i (RDi) version 9.6.0.7, the first release of the popular IBM i development environment in about a year. With this release, IBM is giving developers a handful of new capabilities, including the ability to create procedures out of pieces of code, as well as the ability to test incoming parameters.
Additionally, IBM will increase its number of developer-training programs from 120 this year to 400 next year, said Buell Duncan, general manager of IBM's developer relations. Big Blue hopes that growing the population of developers who use IBM tools at companies and independent software providers will create future opportunities to sell the software, hardware and services for running completed applications.
The developer outreach strategy began in earnest nearly three years ago, but IBM wants to accelerate those efforts, Duncan said. Big Blue is pitching its standards and open source-based approach as a competitor to Microsoft's Windows-oriented developer programs.
What is EGL?
EGL is a programming language that uses familiar programming concepts while abstracting lower level constructs to make developing applications easier. The goal of EGL is to allow developers to focus on what needs to be developed, and not on all the underlying plumbing that typically slows down development and hinders innovation. EGL was originally developed by IBM, then donated to the Eclipse community to order to provide an open, non-properitary langages to use and extend for multi-platform development. EGL, and its predecessor technology, is used by thousands of customers around the world. , but until now has not been easily accessible to the general public. Although EGL helps you create cutting-edge applications, it has a long, rich history. By making EGL open, it is accessbility to the broadest posssible group of people with the intention of increasing adoption of this language that people love after they try it.
What is the EGL Development Tools (EDT) project?
The EGL Development Tools (EDT) progect, is an open source programming technology that simplifies modern application development using EGL. EDT includes the EGL language as well as IDE and other tools to allow developer to quickly create rich internet applications (RIAs). EDT contains Rich UI technology which simplifies HTML and JavaScript development, as well as the capability to create Java-based REST services.
The refresh rate, also known as vertical sync rate, which controls how often the display pipeline scans out to a target. This rate is represented in Hertz (Hz) and stored as a two-part rational number.
