<p><b>New page</b></p><div>==What Is VAXELN?==<br />
(cited from: "AA-EU38A-TE VAXELN V2.0 Users Guide")<br />
<br />
VAXELN is a software product for the development of dedicated, real-time systems for [[VAX]] processors. <br />
The development tools run on the [[VMS|VAX/VMS]] and [[MicroVMS]] operating systems.<br />
<br />
For the purposes of this discussion, a dedicated application is one in which the computers are used to solve a specific problem or, possibly, a set of related problems. <br />
The term spans a wide range of applications, from "workstations" designed for a particular profession to automated industrial machinery and robots.<br />
<br />
In the design of VAXELN, a [[real-time]] application is any in which the system's response to external events is critical. <br />
Such applications include the typical scientific and industrial data processing situations in which the computer's operation has to be precisely synchronized with machines and special input/output devices.<br />
<br />
Traditionally, the design and development of such applications has required expert programmers. <br />
The control of external devices usually requires a programmer intimately familiar with the target computer. <br />
The precise timing and hardware usage requirements of these applications usually require features not provided in high-level languages, meaning that much of the device-specific code has traditionally been written in assembly language.<br />
<br />
Many such applications are best implemented with sets of concurrently executing processes, which have not traditionally been supported by high-level languages.<br />
The execution of concurrent processes, along with other constraints, usually requires a host operating system as part of the application, to manage and schedule the processes.<br />
<br />
In other words, a traditional application programmer in this area had to be an expert in several fields beside his own profession: the design of real-time systems, programming in assembly language, programming in high-level languages, operating systems, and computer architecture.<br />
<br />
The aim of VAXELN is to change this picture, relying mostly on your expertise in your own field rather than on experience with sophisticated programming. <br />
<br />
It gives you the following capabilities:<br />
* High-level programming languages<br />
* No operating system "overhead"<br />
* Concurrent programming<br />
* Transparent network support<br />
* File Service<br />
* Program development and debugging with VAX/VMS</div>Vaxorcist
