A method and apparatus for structuring a program segment are disclosed. The method for structuring a program segment on a computer begins with the step of identifying a series of program blocks in the segment. 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 for allocating computer memory for data elements that are needed for the associated block to execute. The block representative assigns a value to any data element required by the associated block to have a value. The block representative also calls the associated block for execution, receives return of control after execution of the block, and passes control based on available data. |
