Abstract

It is often required that existing program modules, generated by standard techniques, interact with modules that are generated using threaded coding techniques. An interface or procedure to accomplish this will thereby provide the advantages of threaded code to subroutines that use a previously defined coding convention for prologue and epilogue procedures. One situation that can benefit from this occurs when the topic of the threaded code is introduced after a major portion of the code system has been put together. The essence of the combinational process described herein is to decide what the string entry protocol will be. In the case described above, it is essential that the protocol consist of an instruction because the previous machine codes have a prologue starting with machine code.
