For an answer to the first question, you run about the same risk with a
dynamic call as a LINK. Any application program can overlay storage
areas unless you are running transaction isolation. We have very few
problems with COBOL overlaying storage. The biggest problem is
programmers not checking array bounds. If you have repeated calls to
the program in the same transaction, the overhead is supposed to be less
if you use dynamic call because CICS steps in only at the first CALL to
verify the module is loaded.
