CA-IDMS… one of the top mainframe software development and database systems from years gone by. ADS/O for the screens, IDMS calls for database operations. Good stuff, if you know how to use it. Compare to Model 204 (also known as M204), Software AG Natural and ADABAS, CA-Datacom (IDEAL and Datacom/DB), and MAPPER on the Unisys mainframes.More productive than straight COBOL, but not as powerful as the true 4GL environments like Focus and RAMIS. One thing that drives customers to modernize is the license cost. For example, the State of Iowa reports that they saved $296,413 in FY 2005 by negotiating a common license agreement with CA to support 3 agencies. That’s great, that these savings could be had — but it’s sobering to realize that if the savings were that large, the ongoing expense surely isn’t $1,000 per year. It’s still a 6-fingure number. And that doesn’t take into account the fact that all of the mainframe software vendors are raising the fees every year. Then there is the problem of impending retirement of the IDMS knowledgeable programmers. it’s like the Year 2000 (Y2K) problem – just not with the hard deadline. At some point in time, the systems can’t be maintained. So what do you do? The mainframe is secure, it works well, as long as changes are not required and as long as there is money to pay the fees. But the first “rush” change that’s needed in response to new laws or the offerings of a competitor, or the first time 4 or 5 programmers retire at the same time… life gets interesting. If you want...

In computer science, code technology is known as the task by which a compiler’s code generator changes many advanced representation of source code generator into a form that is simply applied by a tool. Compilers typically execute numerous travels over a number of advanced level forms. This method may be used since several computations for code optimization are more straightforward to make use of one at the same time frame and because the feedback to an optimization depends upon the running conducted by another optimization. E-commerce also aids the development of a few architectures which can be focused by a simple compiler since only the last of the code generation levels requirements transforming from target to target with a code generator. The input to the code generator comprises a tree or an abstract syntax tree. The tree is turned into a linear number of guidelines. An advanced plan language like three address code is usually used. Additional stages of selection may or may not be named as ‘transmission generation”, which depends upon when they include an important change in the display of the strategy. A standard code turbine attempts to boost the generated code in some manner because it is added to the transformation from an intermediate representation to a linear group of machine instructions. The turbine may use less coaching, use faster directions, use accessible registers and prevent repeated measurements. Duties which are on average element of a code generation point add the following: Instruction selection: searching for the instructions that you might want to utilize Instruction scheduling: making on the best way to position these training in order. Booking is just a method to enrich charge that will make a very important effect on products. Register allocation: how factors are assigned to model registers Debugging of information technology if expected which means code could be debugged. Utilized in Java, it needs you to produce a few of complicated code that will encourage a code generator to be used. One exceptional example is J2EE in which classes are comprised five by a simple database table in addition to two interfaces using EJB’s and most of the classes are clerical work. Dilemmas must be created manually. Practices in code-generation will help ease the process of fabricating supreme quality EJB code. Run time...

In compsci, code technology is called the procedure by which a compiler’s code generator changes many advanced representation of source code generator into a type that’s easily applied by a device. Compilers an average of execute numerous passes over a number of advanced types. This process can be used since several calculations for code optimization are more straightforward to utilize one at the same time and as the feedback to an optimization depends upon the running performed by another optimization. This business also aids the development of several architectures that can be targeted by a single compiler since only the final of the code generation phases demands changing from target to target with a code generator. The input to the signal generator is composed of a tree or an abstract syntax tree. The tree is turned into a linear series of instructions, an advanced program language like three address code is generally employed. Extra phases of collection may or may perhaps not be named as ‘signal generation”, which depends upon if they include an essential change in the display of the plan. A typical code turbine attempts to increase the generated code in some manner because it is added to the transformation from an intermediate representation to a linear series of machine instructions. The turbine may use less coaching, use faster directions, use accessible registers and avoid repetitive calculations. Duties which are an average of section of a code generation stage range from the following: * Instruction selection: searching for the directions that you need to use * Instruction scheduling: creating on the best way to place these coaching...

Because we write a lot of code very quickly, sometimes people conclude that Java code generation is responsible for the speed we achieve. And, in a way they’re right, although often people have in mind the old style code generators of the 70’s when they say that. This is not your father’s code generator. When we built our technology, we knew there are two things people hate about code generators: first, they write low quality code. The code is not commented and it usually makes use of proprietary function calls. Worse, the organization of the code is such that if you modify it, you will probably lose your changes when the code is regenerated. There is no mechanism to allow you to safely put your custom code into the generated application. Second, the old style generators are inflexible — they will write the code the way they want to do it, not the way you would do it yourself. You can’t modify the generator program, and you can’t get access to the “stock” code it might be using to produce your particular application. If you can live with the results, fine; but if not, you’re stuck. In our first Java code generation solution, we solved those problems, and today that same core technology powers both our Java and .NET offerings. In fact, ResQSoft® Engineer was originally built as a new development tool, and it can be used to develop a new system from scratch, or to modernize an old system where the source code has been lost. It can even be used to create a replacement for that old...

Micro Focus has recently come up with many new options meant to cut expenses and also to cut time, when it comes to building or just maintaining applications used by organizations; some of these options are Micro Focus Cobol, Micro Focus Server Express, Micro Focus DevPartner Studio, Micro Focus Silk4J and Micro Focus for Visual Studio. These options generally enable Java and other devs to modernize their mainframes, by offering a reliable support in the entire cycle that involves editing, compilation and debugging. Micro Focus Cobol– Server Express (RDO) The Micro Focus Server Express will permit client to maintain their programs in Cobol and make the code sourcing on the server that represents the target, preventing them from transferring code between a development environment and the Linux/Unix server, where applications run and are being tested. It also allows the usage of local services and databases. How does it help organizations The RDO along with the Micro Focus Cobol and all the other options is the answer to the needs of any organization in point of debugging and testing application, as close to their production as they can be. This actually translates into a substantial time reduction, because if until now it was a matter of days until a development project could be completed, this can now be done in a few hours, which means more productivity and thus more satisfied customers. Advantages of Micro Focus Cobol and other Micro Focus tools There are many advantages that this option has for its users and these are only a few of them: – Increase of productivity due to time reduction of...

What is Micro Focus Cobol? According to Wikipedia COBOL is one of the most ancient programming languages. Its name comes from the words COmmon Business-Oriented Language, a definition for its main use in finance and other businesses, as well as in systems of administration for governments and companies. Its date of birth is18th of September 1959. A bit of history of Cobol In the second part of that year, a team consisting of several researchers coming from different sectors of the private industry but also from the government and educational departments got together with the purpose of creating a different technical approach to a common business language. 3 government agencies joined the battle, among which there was also the US Air Force . There were 6 computers manufactures, users, on one hand, and the University of Pennsylvania Computing Center on the other hand. A year later, the first compilers for COBOL were implemented on two different computers, demonstrating that compatibility is possible. And that was only the beginning. Today, after 40 years, Cobol is a programming the language dedicated to stable applications for businesses, while MF Cobol is the power engine behind the modern Cobol. The engineers continued to move forward to meet users’ demands. They were there when tools such as Visual Cobol was born, so that Cobol applications is able to run on JVM, Linux or Windows. MF Cobol in Business Micro focus COBOL has been the dominant programming language in the business domain. Around the year 2000, the company estimated that there were about 300 billion lines of computer code in use in the world and...
