To run the cobol program, first it go through compiler to get object code, which will go through LINK EDIT to produce Load module, which would be a executable code. For the Dynmic calls, both calling and called programs are compiled and linkedited separately to produce the load modules, but we have to use dynam compiler option while compiling the main pgm.

Link edit is the process of linking of object codes of similar programs to form a single executable load module.

Linkage of object codes of mainprogram and subprogram is done during execution.  

Load Module: The object code converted into Load Module (Machine readable form) by using Link edit that's common in COBOL.

    But in Dynamic call, first we have to submit the sub progs later we can use that in Link  section in COBCOMP. That's the procedure.
