Running Debug Manager as a started task by using environment variables

Starting from z/OS® Debugger 16.0.4, Debug Manager supports passing parameters through environment variables.

During its startup, Debug Manager checks whether any environment variable has the same name as its parameter, such as INTERNALPORT, EXTERNALPORT. This approach allows passing parameters by using XL C/C++ _CEE_ENVFILE parameter as follows.
