I thought all VMS executable files, VAX, Alpha and Itanic, were fixed length
512 byte records, meaning all executables were always an exact multiple of
a disk block in size.

(doesn't mean all 512 bytes have to be used each time. I suspect any
HELLO_WORLD.EXE likely has a text psect where only a few bytes are used
but consumes 512 bytes [times page_size?] in the .exe)
