tcp-ip

Designed to enable professional mainframers to apply existing knowledge and skillsets in the UNIX environment. Not for beginners with no knowledge base in either environment. Gives many helpful comparisons, for example:

Mainframe = SDSF da/i/o/etc.. Closest Unix Equiv = lpstat/ps/who/vmstat/iostat

Mainframe = partitioned data set (PDS) Closest Unix Equiv = subdirectory

I believe would benefit both midrange and mainframers working in a multi-platform environment. If nothing else it helps bridge the language barrier between the two groups and takes some of the mystique out of the 'other side'.

Describes Unix using the mainframe as equivalents. Very interesting and helpful.
