IBM Mainframe Forum

Hi all,
Can someone please post some doc or any reference to any good website for File Handling in assembler....i need this urgently..
Thanks in advance

Hello and welcome to the forum,

What "File handling" do you have in mind? Typically, a DCB is defined and then the file is opened, read or written, and then closed.

There is probably more assembler info at this link than you will ever want

The 2 main manuals you might want are the Language Reference and the Programming Guide.

If you are just beginning with assembler, you might look at:
http://www.murach.com/books/mainframe.htm
There is an MVS Assembler Language book written by Kevin MqQuillen and Anne Prince that is very good for beginners.

My favorite manual for file handling is the DFSMS Using Datasets manual. Good explanations and some assembler examples. Look at http://publibz.boulder.ibm.com/epubs/pdf/dgt2d460.pdf
