  • Programming Languages: What About COBOL?

    In my previous post, I continued a discussion about Basic Assembler Language (BAL) that I had begun the week before. BAL is still useful is a funny way of putting it, because in certain contexts BAL is indispensible. Consider this: Everyone who makes a living as a programmer should write in the BAL of their favorite machine so they can grow from the lessons that this experience teaches them. So what about COBOL, how is it doing?

    The Dance Between Machine and Its Language

    With this post, I want to discuss one of the most wonderful and challenging elements of z/OS—its Basic Assembler Language (BAL).

    Building on NetView: Tivoli System Automation for z/OS

    In my previous post, I wrote that NetView can be used by itself to automate systems and networks or it can be used as a base upon which can be added other automation products to speed up the process of automating a system. The other automation product I was writing about is Tivoli System Automation for z/OS.

    Automating From Start Up to Shut Down: NetView

    In my previous post I wrote about SYS1.PARMLIB and made a specific focus on members that pertained to automation including COMMNDxx, IEFSSNxx and MPFLSTxx.  In this post I want to explain the role of NetView in system automation.

    z/OS Jewel Keeper: SYS1.PARMLIB

    SYS1.PARMLIB contains many initialization parameters in a pre-defined form, contained in a single data set, minimizing the need for the operator to enter parameters. Here is a description of three sample members that relate to automating z/OS systems.

    Focusing on Usability and Automation: Message Processing Facility

    In my previous post I wrote that Job Control Language (JCL) is very straightforward. If it is complex at all it is because it is used with programs whose conventions are not always understood. In this post, I want to explain a component of z/OS that you might not know about.

    Essential and Under-Appreciated: Job Control Language

    In my previous post, I wrote about the VSAM and how many application programmers and support personnel use it here. Everyone who works with z/OS has probably had some contact with the VSAM access method and its utility named IDCAMS. This is true to an even greater level for Job Control Language (JCL).

    Abstract and Precise: System Modification Program

    In my previous post, I wrote about the System Management Facility. It is one of the components of z/OS that is enormously useful and implemented with brilliance. Another component that is remarkable is the System Modification Program Extended (SMP/E).
