Mainframe Assembler Language 2.0

Those that still follow my blog from my days working in the IBM mainframe arena might be interested in the following.

One of the stalwarts of software at IBM, and self described grand poobar of High Level Assembler, John R. Ehrman has a 1300-page 2.0 version of his book “Assembler Language Programming for IBM System z™ Servers ” and it’s available in PDF form here. There are a wealth of other assembler resources that John has contributed here on ibm.com
