The unit testing library routines use the mfunit_prototype.cpy copybook for call prototyping. If required, it is available from the cpylib directory of your product installation directory. Another of the unit testing copybooks (mfunit.cpy) contains a level-78 constant, MFU-ASSERT-FAIL, which you can use in your programs to invoke this library routine.
