launch — a shell on a MCP node, ¹ provisioned per your current SSO context. ²

MCPCMS presents the operator display terminal CONTROLLER for MCP ops and the default or "CANDE" MCS³.

Restricted to AKPERSONs (see Entitlements), and whitelisted stations .

A running SPO counts against launch limits.

ABORTED, ACTIVE, COMPLETEDOK, or STOPPED are completion codes for launch job but in the wild it's not run.

Launch code ABORTED implies additional info in your home profile DS control blocks.

¹ Resource limits are dynamically set except for F class which always gets the system limit if there is one.
² MCP nodes must have sub-millisecond ping. Set parameters for your own AWS or Linode accounts or your manually provisioned hosts in the Remote Inventory DS block in your home profile.
³ MCS: a message control subsystem of a MCP.


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 MCS. Some other commands do map to the new system context though and they are developed in a similar fashion to WFL with an additional shell mode command cande like the lang specific subshells in the next §, which invokes the MCS command processor at a mcpcms prompt.

The command processor is also available as a pane in the WebKEE legacy SPA and the CANDE MCS is the default ubiquitous DCP/MCP MCS. CANDE is used in current Unisys MCP but neither it nor the MCS have their former prominence when the OS runs under Windows.


is derived from zsh for MCP and the shell variant set for it in /etc/shells. In an authenticated session, the launch link normally results in a WebSSH session with this shell. 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.

# save as <fileName> and invoke with <fileName>  <connect-spec> where            
#  <connect-spec>::= <ipV6Address>:<port> | <ipV4Address>:<port> | FQDSA<whiteSpace><FQDSAgentName> 
#  FQDSAgentName ::= <agentId>@<domain>[:<port>]
#  and the values are displayed in the DCMS account profile.  
if [ -z $2 ] then
  ssh  $1
# Get connect values from FQDSA.
PARMS=$(curl -L $FQDSA)
ssh $PARMS

mcpcms is implemented for Linux first then MacOS. The intent is to support mainframe OSes after that, specifically the Hercules version of IBM and the Windows based version of Unisys MCP. Core Domain Space uses either AWS or Linode to dynamically provision whole hosts as MCP nodes and nodes may also be created as composed containers on an existing host.


is derived from the MCP 12 WFL job control model, runs underneath mcpcms and serves as the physical base of MCP/DCP elements.

Burroughs WFL is basically just an inspiration and point of departure to a WFL

  1. 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 nascent 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:

Subroutine DeclaratorLanguageIntrinsic
CLCommon LispNo
HSHaskell No
System Internal
UNITAlgol 68Yes
MCP Block Types

Intrinsic means the lang is native to MCP/WFL and doesn't require COMPILE or BIND to produce a RUNable title.
Job titles are bound to files by the cande WFL command after which they can be STARTed.
The WFL compiler translates JCL to A68, MINT, and assembly which are run by genie, mint, and da Fe, respectively.

The namestyles are a homage to MCP and VM/CMS main frame operating systems which are both still in use and Unisys WFL (Work Flow Language).
