I "suspect" no one individual came up with any of those
subjects. Remember, the S/38 took a LOT of it's ideas
from the S/36. The relational data base came from the
big iron guys who had it for years prior to the S/38.
The calls came from the big iron folks. The S/38 was
truly a collection of ideas from everywhere.

CLP was a combo of OCL(S/36) and JCL(MVS) in my opinion.

The S/38 was a very odd bird at the time but really a
big collection of "other" ideas that finally got put
in a single machine.

The MI abstract layer was the first of "new" ideas.
This so called "microcode" was really somthing new at
the time. It later proved to be a VERY good idea.

Of course the S/36 had microcode several years earlier
from it's beginning in the S/34 and even much earlier
with the S/3.(back when the earth's crust was cooling)
