Hercules/MVS Turnkey - MVS on a PC

I started my career as an operations analyst. Worked my way up to be a systems programmer for MVS. During my career as a systems programmer, I wrote several assembler programs on MVS. Those were interesting days and nights.

I was actually surprised to know that I can install MVS on my PC. The same version of MVS I supported - MVS 3.8! I know, it's not state of the art. It's just 24 bit addressing! But I think it is a good tool if one wishes to learn about operating systems in general and MVS in particular. Or if one just wants to relive old glory days in writing assembler code.

SYNCSORT Advanced Features

Many use SYNCSORT for sorting files. But SYNCSORT can do a lot more. It can be used to format records. Because of this feature, it can be used for other purposes. (These features are also available in DFSORT, although some features work differently in DFSORT).

Unix System Services (USS)

Probably unknown to many in the industry, the IBM mainframe runs Unix System Services (USS) with the z/OS operating system. USS runs as a separate address space in z/OS as a started task.
