IMCB$V_PARENT_PROT What is it good for?

Hi

If someone out there has a copy of the Internals and Data Structures Manual,
could they please check to see if there is any info in there about the IMCB
and in particular the PARENT_PROT bit?

Any and all documentation would be useful. What's it all about?

Regards Richard Maher

PS. This from lines 3334 to 3338 in SYSIMGACT.LIS 19-Nov-2004

"Also set the PARENT_PROT bit to ensure subsequent activations of images
references by this one are checked."

PPS. Does anyone know if S. Davidson gets upset at unsolicited emails?
