RE: Give simple program example for Dynamic link and Dynamic call in COBOL?

| Usually in COBOL the subroutines are compiled and linked to the load module at the time of compilation and if we are calling the subroutine only a few times, then may not worth keeping in the memory unnecessary. This is known as STATIC CALL. So COBOL facilitates another mechanism called DYNAMIC CALLs to avoid this prob. In dyanamic call, the subroutine is not a component of the main program. It is compiled separately and is only moved to main memory at the time of CALLing. Hence it saves memory and overhead. |
