COMMON block page alignment

I'm trying to create a shared memory region (using shmat, et. al.) to use for IPC (my common blocks are huge.......close to 100M each). Problem I'm having is the start of the COMMON block needs to be page aligned in order for shmat() to work properly. Changing the value of the -align flag only appears to pad the elements of block, not altering the start of the block itself. How do I get the compiler to have the block start on a page boundary?

TIA

See the !DEC$ PSECT ALIGN attribute in the Language Reference Manual.
