WTO / WTOR is the means to communicate with the operator, either human or 
automated. The system provides that communication path. It does not need an 
setup on the program / JCL side. It should not be misused as cheap replacement 
for a "real" application log written to a dataset. 

If you really need some log information to appear in the jobs JESYSMSG log, use 
WTL. It will not disturb neither operators or automation.

If you care to write a proper program documenting the actions done, don't shy 
away from OPEN/WRITE/CLOSE. IMHO, this is part of good programming style.
