<< 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.
Of course, CICS' lack of involvement comes with a price. There is a good
comparison of LINK vs static call vs dynamic call in the CICS Application
Programming Guide. Refer to that as a starting point.
