Description
In the past, I hosted virtual instructor-led training sessions for Mainframe resources and recorded them as they happened. These unedited videos, available on Udemy, offer an immersive experience with participants' voices and questions intact. They faithfully replicate the live session atmosphere, featuring practical demonstrations and explanations on the Mainframe server, rather than relying heavily on PowerPoint presentations.
