Hi

I have a question for experts.
What is the meaning of PIP on okuma osp systems?

Thanks for replies

Okuma operating system ( as well as the Okuma CPU ) is related to the CP/M which is predecessor of DOS. CP/M and OSP are utilising different approaches to sector access of disk. Their predecessors are tape sector access based operating systems. The PIP function comes back from the tape operating system and it is universal unidirectional input and output streaming tool for a sequence. Means, not a parallel transfer. Signals flow both directions, the stream flow is one directonal. Due to it's flexibility and growing demand it was later elaborated and used for parallel data exchange as wel ( VAX VMS 730 for instance ) on the later Unix OS. It is only one way for input and output data stream ( including even terminal Display and console terminals ) at that old operating systems except of keyboard input.
It is not abbreviation in my opinion. In order to use the pip command you need to key in a whole line of commands, operands and parameters. Back then it was the only one command requiring long line input - pipe. By keying in all the operands, options and parameters you create a pipe.
There was no habit of abbreviations back then. Operating system contained limited set of ( built in ) commands - List, Dir, Cls, Find, Type, Peek, Poke, Pip ... I don't remember more There are no directories ( catalogues ) on the CP/M, Thus OSP is more progressive.
Piping in Linux is quite different thing and there are many other meaning of PIP abbreviation today, not related to OSP in any manner.

Thank you for your quick reply.

Peripheral Interchange Program (PIP)

or interface :-)
Yes, of course it is very likely.

Back in the stone age, I was a Kaypro Computer service tech.

And the original Kaypro systems were CP/M based. And yes PIP is a CP/M acronym for "Peripheral Interchange Program". More on CP/M PIP here: https://en.wikipedia.org/wiki/Periph...change_Program

Okuma says PIP is Peripheral Interface Program
