JCL is not generally taught in schools and Universities, so people who need to use JCL generally have to learn it on the job. The Plan 9 operating system pushed this model even further and eliminated the need for additional mechanisms. JCL is a language like any other. Whether your job is programming, operations, or anything else, whatever your reason for wanting to learn JCL, this book is designed to help you. So your co-workers can be of only limited help to you with learning JCL. Hopper was always looking to speed up the writing of code.
It will help you learn JCL in the first place and thereafter it will be a useful reference you can keep coming back to, like an old friend, to help you out when you get into trouble. When you read the book straight through in this way, you will come across a lot of obscure but useful information to help you in your routine use of MVS. You use JCL to tell the mainframe how much memory and other resources your programs will need, how long each program should be allowed to run, what order to run the programs in, where to get the input data, where to put the output data, and so on. Things are explained in plain ordinary language, so even if you have never before seen one line of JCL, you should have no trouble with the text; and by the time you get halfway through the book people should be starting to see you as an expert, probably to your great surprise. She maintained a catalog of sub-routines, which could be reused. Once explained, all seems clear—as with most things.

Once explained, all seems clear, as with most things. It was taped in the logbook, as the first actual bug found.
JCL is a language like any other. Capital was hard to come by. For the most part they have a difficult time, largely because the people they learn from dont have a good grounding in JCL either.
Because, contrary to its reputation, JCL is not particularly difficult; it just has esoteric aspects that make it seem difficult if you have nobody to explain things. It achieved its reputation by its interactivity, by providing the software at a nominal fee for educational use, by running on inexpensive hardware, and by being easy to adapt and move to different machines.
The use of a computer by business corporations was still in its nascent stage. Over time, the leading developers of Unix and programs that ran on it established a set of cultural norms for developing software, norms which became as important and influential as the technology of Unix itself; this has been termed the Unix philosophy.
Those other people only learned enough to get by when doing a few things they needed to do; and those few things may not be the same things you need to do now. Those other people only learned enough to get by when doing a few things they needed to do; and those few things may not be the same things you need to do now.
Three different groups - short, intermediate and long-range were formed. The Plan 9 operating system pushed this model even further and eliminated the need for additional mechanisms.
Thats why you want a good book on it now. You can also read the book as an introductory text, from start to finish. This section is particularly useful for those who want to know some of the more advanced and yes, usually esoteric aspects of JCL. JCL is a language like any other.
The focus on text and bytes made the system far more scalable and portable than other systems. Having good guidebooks saves you a lot of learning time. Category: Computers. Linux distributionsconsisting of the Linux kernel and large collections of compatible software have become popular both with individual users and in business.
