i have got this info from another person. check this.
My name is Tony Kuhlman. I do most of the end-user support for DYL280 here at Michigan State University.
Here is some background information about DYL that may answer your questions:
DYL280 and Vision:Results are the same computer programming language. They are updated versions of a product originally developed by a company named Dylakor. After several updates and revisions, Dylakor marketed the language under the name "DYL280". They sold the product rights to Computer Associates, who renamed the language "Vision:Results" and made it part of their suite of Vision products. But they are one and the same product, and here at this installation, it is usually referred to as "DYL280" or just "DYL", which is pronounced "dial".
The language is used on IBM mainframe computers. It is very good at quickly selecting and organizing data from sequential and indexed files, and can be used to navigate relational databases as well. I am not aware of any versions that will run on a PC or mac platform, but it is possible that CA may have developed such a tool. The language runs in either an interpretive mode, much like Basic did years ago, or it can be compiled and run from a Loadlib, like Cobol or PL/1. We offer it as a tool to many users and departments here on campus. Some are IT professionals, some are professors or instructors, some are secretaries and clerks. It is fairly easy to learn and use. Our users write both ad-hoc programs that can generate a report of file quickly, as well as create jobs that are used daily, weekly, monthly, etc.
For more information on the product, I recommend you go to the Computer Associates website and search for "Vision:Results". They would be able to give you more current information than I would, and probably in more depth as well.
You can see our training materials for DYL280 on our website at http://dataadmin.ais.msu.edu/Workshopfrontpage.html. If you work at MSU and are authorized to use our data, we offer free training as well. If you're not part of the MSU community, however, there's not much else I can offer you except that you are free to review the training material on the website. Keep in mind that our training material was written specifically for the way we use DYL here at MSU, and it may or may not work the same way on another system.
