Primitives in CPAM

Pre-invocation:

SETUP: set up a connection to a megamodule

SET-, GETPARAM: preset / get attributes in a megamodule

ESTIMATE: get cost estimation for optimization

Invocation and result gathering:

INVOKE: start a specific method

EXAMINE: test status and progress of an invoked method

EXTRACT: extract results from an invoked method

TERMINATE: terminate a method invocation

TERMINATEALL: terminate the connection to a megamodule

Termination:

All primitives are procedure calls ==> asynchrony in method invocation
