1.1.2.5 Modification of CA MICS Source Code

Replacing parts of CA MICS logic, prototype members used for
generation, or other material with installation-unique coding
is a type of modification that should not be undertaken
lightly.

Chapters 4 and 7 of this manual contain guidelines for
users who want to investigate the possibilities of
implementing such modifications.  If such changes to the
actual source code of CA MICS are considered, pay close
attention to the discussions of how this type of modification
increases your dependence on a particular release of CA MICS.

However, given the above, it is quite possible to modify the
CA MICS system at the source code level. Many CA MICS users
have had excellent results in meeting unusual requirements by
carefully controlled modifications of this type.  Examples of
requirements that necessitated source code modifications are:

    - Job step accounting

    - Unusual requirements that affect the calculation of
      the ZONE data element

These unusual processing requirements cannot be treated
through other CA MICS tailoring or exit facilities. The key
to the success of such modifications is to follow the
instructions in chapters 4 and 7 and to keep complete and
accurate records of the changes made.
