Subject: Re: ECB parameter on attach
If I understand you correctly, the answer to your question is no.
If an issuing task supplies an ECB with an ATTACH macro the system posts it
complete when the subtask created by the ATTACH completes its processing.
This is usually done so that the attaching task can use a WAIT macro to wait
upon and be notified by the system of the completion of the subtask.
The system does not, however, remove the program object or load module
executed by this subtask from storage, which is an advantage if subtasks
that use it are attached repeatedly. For this reason the attaching task
must issue a DETACH macro for the subtask before it itself terminates.
If instead neither an ECB nor an ETXR parameter is specified in an ATTACH
macro the system does the clean up, removing the executable from storage
after it completes its processing.
Note also that, at least in new code, you should now be using ATTACHX
instead of ATTACH.
