need to know good assembler manual

[deveshjogal]

Hi all

I work on OS/390 and wish to learn assember programming. When I went on MVSHELP.com there many books listed. could anybody suggest me the best one for a beginner. I have a manaul of 'Assembler H' on mainframe. Is it diffent from High level assembler?

Thanks in advance

Assembler H is older than High Level Assembler (HLASM). HLASM allows mixed-case, longer, programmer-assigned names and makes many, many other improvements. It's a really nice assembler.

There are probably some things that should influence your choice of textbooks. Do you really want to learn assembler to write application code in it, or are you really after learning about the 360/370/es9000/zSeries architecture (i.e. machine language)? Perhaps you simply want to write some simple OS-dependent routines like many system programmers? Or perhaps you're a systems programmer and simply want to better understand the assemblies the vendors give you to run?

At any rate, knowing what you plan to do with it may influence the recommendations you get.

Regards.

I need to do maintenance work of assembly routines. Many of them manipulate files. Also I may need to write a few if required.

Thanks

MVS Assembler Language ISBN 0911625348 published by Murach and Associates $40.50 (

http://www.murach.com/index.htm)

should do the trick. (Used copies available from

http://www.amazon.com.)

Like all of Murach's books, it is well laid out and provides an excellent place for a beginner to start.

To move beyond the basics, you'll need additional references.
