A method, for use with a computer having memory, for structuring a program segment, is described. A series of program blocks in the segment are identified. Each block is a functional piece of code in the segment and has at least one point corresponding to at least one of entry and exit, in such a manner that the entire segment is divided into blocks with each block being situated in an execution path along which the segment executes in a downstream direction. With respect to each block, a block representative is associated. The block representative allocates computer memory for data elements that are needed for the associated block to execute. The block representative also assigns a value to any data element required by the associated block to have a value. Additionally, the block representative calls the associated block for execution, receives return of control after execution of the block, and passes control based on available data.
