The Question is:
how do you interpret the event flag field when using "show process/continuous"?
We can't find any documentation regarding the format for this field!
The Answer is :
The value displayed by SHOW PROCESS/CONTINUOUS currently contains
the PCB$L_EFCS and PCB$L_EFCU local event flag cluster longwords.
The structure of the privileged-mode event flag wait mask (EFWM)
and the other event flag data structures in the process control
block (PCB) are not formally documented by OpenVMS -- that said,
the Internals and Data Structures manual and the OpenVMS source
listings CD-ROM set will be of interest.
