Instructor-led training (ILT)
Onsite dedicated training (OST)
This course teaches techniques for creating DCL command procedures for automating user and operating system tasks on an OpenVMS system, including DCL syntax, design and implementation, batch processing, lexical functions, and running applications from a command structure. The course incorporates our Lab+Lecture format.
- Attendees must have taken OpenVMS Utilities and Commands or have equivalent professional experience before attending this course.
- No prior programming experience is assumed; however, knowledge of some programming language (BASIC, C, FORTRAN, etc.) and programming language concepts is helpful.
- Advanced users of OpenVMS, application programmers, system programmers and system managers.
Ways to save
- Save with the HP Care Pack education service offerings.
- Save with four or more students in the same class. An onsite dedicated training course (OST) at "your location or ours" can save you even more!
Benefits to you
Upon completion of this course, students will be able to create, modify and debug command procedures on OpenVMS systems. They will be able to understand how existing command procedures work.
