-
- As many of you may know SRI is part of a team working on the National
- Software Works project. In the course of our work we have developed a
- Procedure Call Protocol to be used between the modules which make up
- the NSW. We are interested in your comments on this protocol. Please
- foreward your remarks to either: 2

- This note announces the release of the second published version of
- several National Software Works (NSW) and Procedure Call Protocol
- (PCP) documents. Version 2 is SUBSTANTIALLY different than Version 1;
- it and all intermediate, informally distributed PCP documents are
- obsoleted by this release. 3
-
- Each of the following documents is available on-line in two forms: as
- an NLS file and as a formatted text file. The Journal number (e.g.
- 24459) refers to the former, of course, and the pathname (e.g.
- [SRI-ARC]<NLS>PCP.TXT) to the latter, accessible via FTP using
- USER=ANONYMOUS and PASSWORD=GUEST (no account required). Let it be
- emphasised that files indicated by pathname of the form
- [SRI-ARC]<NLS>name.TXT are ASCII text files not NLS files. 4
-
- The specifications are contained in the following documents: 5
-
- HOST (24581,) "NSW Host Protocol" 5a
-
- This document describes the host level protocol used in the NSW.
- The protocol is a slightly constrained version of the standard
- ARPANET host to host protocol. The constraints affect the
- allocation, RFNM wait, and retransmission policies. 5a1

-
- EXEC (24580,) "The Executive Package" 5i

-
- BATCH (24583,) "The Batch Job Package" 5k
-
- This document describes a package that runs in the setting
- provided by PCP. It includes procedures for creating and
- deleting batch jobs, obtaining the status of a batch job, and
- communicating with the operator of a batch processing host. This
- package is implemented at the host that provides the batch
- processing facility. 5k1

- NWG/RFC# 674 JBP 11-DEC-74 18:04 31484
- RFC 674; PCP Announcement
-
-
-
- This document discusses the process of utilizing a batch
- processing facility to complete a programming task in the NSW
- environment. This same activity in another environment might
- utilize a remote job entry system. 5l1
-
- Pathname: [SRI-ARC]<NLS>RJE-MODEL.TXT 5l1a
-
- LLDBUG (24579,) "The Low-Level Debug Package" 5m
-
- This document describes a package that runs in the setting
- provided by PCP. It includes procedures for a remote process to
- debug at the assembly-language level, any process known to the
- local process. The package contains procedures for manipulating
- and searching the process' address space, for manipulating and
- searching its symbol tables, and for setting and removing
- breakpoints from its address space. Its data stores hold
- process characteristics and state information, and the contents
- of program symbol tables. 5m1

-
- TBH (24656,) "NSW Requirments on Tool Bearing Hosts" 5n

- bearing host and the interfaces to the operating system
- components by various PCP packages. 5n1

- Pathname: [SRI-ARC]<NLS>TBH.TXT 5n1a
-
- BOXES (24584,) "Black Boxes in PCP" 5o

- defined by Millstein and Warshall into the setting provided by
- PCP, especially the File Package and the Executive Package. 5o1
-
- Pathname: [SRI-ARC]<NLS>BOXES.TXT 5o1a
-
- The document on the Host level protocol, HOST, is a suggestion for
- some restrictions on the regular ARPANET host protocol for use in NSW,
- this topic has little impact on the remainder of the NSW protocols.
- The reader is urged to begin with the major Procedure Call Protocol
- documents. 6
-
- The document on PCP is the place the interested reader should start.
- It gives the required motivation for the Protocol and states the
- substance of the Protocol proper. 7

-
-
- The reader may then proceed to the next three documents: PIP, PSP and
- PMP. The latter has the most relavence to the casual reader; the
- programmer faced with coding in the PCP environment should read all
- three. 8
-
- The three documents PCPFMT, PCPHST, and PCPFRK specify low level
- details of the communication formats and are of interest only to PCP
- implementers. 9
-
- The documents EXEC, FILE and BATCH describe procedure packages to be
- implemented as appropriate to provide the services of the
- accounting/status/usage statistics subsystem, the file subsystem or
- batch processing subsystem respectively. 10
-
- The document RJE-MODEL describes how a user would utilize various
- tools in the NSW in the process of carrying out tasks he might in the
- absence of NSW achieve using a remote job entry system. This should be
- read with the document on BATCH.
- 11
-
- The LLDBUG package specifies a debugging package that operates in the
- PCP environment. 12
-
- The document called BOXES describes a mapping between the PCP
- mechanisms and the File Package procedures and the Black Boxes needed
- by the Works Manager. 13
-
- The document TBH speaks to the requirements placed on the Tool Bearing
- Host. This document indicates how and where various PCP packages
- interface to an operating system. 14
