MCP-CMS — a platform for the Domain Control Program, with an aesthetic in homage to the Burroughs and IBM OSes.

¹ Resource limits are dynamically set except for F class which always gets the system limit if there is one which for billable accounts there isn.
² Set parameters for your MCP nodes cloud provider in the DS Dashboard control blocks in your DCMS account.

† This page and About DCP are top level specifying stories, cog arch internals aren't divulged as I mean them to be adaptable without notice, everything else is source accessible by devops users.

tl;dr

MCPCMS presents the "CANDE" MCS³ for DS users.

AKPERSONs (see Entitlements), and whitelisted stations can connect with the link above or in a running SPO to a MCP running it.

The attempt, if it reaches the MCP, results in completion codes reported in DS control block displays in your DCMS profile.
Only ssh access from the wild, but this page will attempt, using your SAR credentials if the session role is greater than 1.
MCP operator messages will go to your ODT message queue.

³ MCS: a message control subsystem of a MCP. MCP 3.3 CANDE Reference Card
MCP 15 System Commands

CANDE MCS

MCP-CMS connects via an MCS which is often referred to as the CANDE MCS although it is more general than that being the default ubiquitous DCP/MCP MCS. Upon mcpcms connect, like the lang specific subshells in the next §, an additional command cande can be used which will process the MCP-CMS system commands analogous to those in the MCP 15 document above. The system command processor is also available as a pane in the SPO.

In Burroughs MCP, the CANDE MCS was used ubiquitously. I recall using a full screen editor which i think fed CANDE. The text edit functions are obsolete and not part of the mcpcms cande. CANDE is used in current Unisys MCP but neither it nor the MCS have their former prominence when the OS runs under Windows.

mcpcms

A modified zsh for MCP serves as analog of the CMS from VM/CMS. Upon successful connect, the launch link above results in a terminal session with this shell in the browser. Aside from the modification for the MCP machine model, it is otherwise just zsh however the following (mode) commands are available to establish different shell behaviour in support of the KEE:

• shcl (common lisp nature)
• shhs (HsShellScript, haskell nature)
• upsh (prolog nature)

Lisp and prolog implementations are variable, and multiple can be combined but shcl and upsh themselves use sbcl and swipl, respectively. mcpcms can be accessed with ssh using the following script. Using the FQDSAgentName syntax is equivalent to what the launch link does in an AKPERSONs session.

#!/usr/bin/bash
# save as <fileName> and invoke with <fileName>  <connect-spec> where            
#         
#  <connect-spec> ::= 'skip' <FQDSAgentName> | <connect-spec>
#  <connect-spec> ::= <ipV6Address>:<port> | <ipV4Address>:<port>
#  FQDSAgentName  ::= <agentId>@<domain>[:<port>]
#
#  and the values manually supplied from control blocks in the DCMS account profile where connect attempt results will also be available.  
#  The skip literal indicates the station where the script runs is trusted and the responsible AKPERSON is the operator.
#
if [ -z $2 ] then
  ssh  $1
  exit
fi
#
# Try a connect based on just the FQDSA assuming an eligible station.
#
FQDSA=makecell.meansofproduction.biz/?FQDSA=$2
PARMS=$(curl -L $FQDSA)
ssh $PARMS

mcpcms is implemented first for Linux natively running or containerized in docker on Mac and Windows then for the Hercules version where VM/CMS replaces the modified zsh for that special path. Cloud compute resources are dynamically provisioned using either system inventory or user supplied provisioning credentials with supported cloud vendors.

WFL

has eponymous origin in the MCP 12 WFL job control model and supports the DCP with a line of demarcation between the minimalist MCP and its extension specific to DCP which is meant to protect properties of its internals. A way to think about it and my design intent is that MCP is a basic unix cluster machine to host any common mix, while the WFL machine is a private specialization.

Unisys WFL is just a point of departure to our WFL. In Burroughs systems, WFL didn have as high a profile as IBM JCL, the main punch of the overall system, in an industry installation, would be its system of transactions and these ran from a database which the Burroughs architecture delivered seamlessly without WFL to terminals as a special db stack. Our WFL is the central driver and basis of our MCP architecture

1. is built for the MCP machine model
2. which is a prime driver for the development of that model
3. with code blocks containing text of other supported langs

As far as the elaboration of JCL statements and so forth WFL is developed in a bottom up prototyping style without any spec other than the mainframe reference and the DCP/MCP concept, so there will be no documentation for some time other than the text of actual jobs. № 3 above is implemented by variants for the SUBROUTINE statement, with the same attachment of BEGIN and END bounded blocks:

MCP Block Types

Block Declarator	Language	Intrinsic	Purpose/Role
Front
CL	Common Lisp	No	Lateral R
HS	Haskell	No	User Applications
JOB	WFL	Yes	JCL
LP	LogTalk	No	Lateral L
PL	Prolog	No	Plain Prolog
Back
MINT	MINT 3	Yes	MCP direct interpreter
SUBROUTINE	A60	Yes	JCL
UNIT	A68	Yes	System Applications

Intrinsic means the lang is native to MCP/WFL and doesn't require COMPILE or BIND to produce a RUN eligible object title.
MAKE binds job titles to files executable by the cande MCS with the START or SCHEDULE commands.

WFL(JCL) job streams are translated from source text to A60/C, A68, and MINT then compiled and linked to the Barton machine, or interpreted by genie or MINT, respectively. WFL(JCL) is A60 translated to C, compiled and bound, interspersed with the JCL statements interpreted by the B machine. Non-intrinsic code forms unified code trees in the DGUI and is maintained there under the control of the governing build statements and commands. Thus, a general WFL job orchestrates an application divided into system part executed by the B machine and application parts executed in the OS image extended from the base OS by the B machine.

'WFL' used without the JCL qualifier or 'WFL workframe' refers to general source processing framework of the high level part of the DCP. Build statements and commands refers to COMPILE/BIND/MAKE.

The namestyles are a homage to MCP and VM/CMS mainframe OSes, both still in use and Unisys WFL (Work Flow Language). The machine thus defined will be ported to other cloud vendors (Google, Azure, et. al.) after workout in Akamai (linode) and AWS.
