2949.6I have a need for 64-bit pointers in DEC C++/Alpha/VMSDSPAC9::RETHMANNick RethmanTue Feb 04 1997 13:0512
Hi,

I have a need for a CXX with 64 bit pointers on VMS.  I also know of
one other person here in the CAD group who also has this need.
Currently, the users of our tools are hitting the 1G byte VMS limit.
The easiest solution for us would be to compile with 64 bits to get
around this problem, however I was surprised to find out that there
was no support for VMS CXX with 64 bit pointers.  Do you have any
update on when this will be available?  Feel free to send me email if
you need more information.

Nick,
	No status change since Charlie's note.  His note didn't reflect the true
difficulty on VMS.  Since the object model on VMS uses 32 bit pointers for
the run-time tables needed to support the virtual function call and the
pointer-to-member language features, supporting the full language use of 64 bit
pointers would require breaking the object model.  So unless there is a
groundswell, that can tolerate a modified version of the object model on VMS,
64 bit pointers won't happen soon.
