3. A method of regulating operation of a computer using computer program instructions conforming to a structure characterized by: (a) an invocation string having (i) a string identifying an operation, (ii) an invocation destination list identifying, for each operand sourced externally to the invocation string, a place from which the operand is sourced, and (iii) an invocation source list identifying a place for a result of the operation; and (b) a definition string associated with the invocation string and having (i) a resolution string defining the operation, (ii) a definition destination list identifying, for each operand sourced external to the definition string, a place from which the operand is sourced, and (iii) a definition source list identifying a place for a result of the operation; Where the method comprises: (1) instantiating an operation of a first invocation string upon completeness of necessary operands identified by a invocation destination list of the first invocation string, where an element in a invocation destination list of a second invocation string identifies an element in a invocation source list of the first invocation string; and (2) resolving the instantiated operation of the first invocation string according to a definition string associated with the first invocation string including a step of coordinating a content flow with an operation of the second invocation string that has a dependency relationship with the instantiated operation of the first invocation string.

The method of claim 3 where coordination includes an express signal of an availability to receive data.
