Alpha and VAX systems. Specifies the minimum number of contiguous, uninitialized pages that the linker must find in an image section before it can extract the pages from the image section and place them in a newly created demand-zero image section. By creating demand-zero image sections (image sections that do not contain initialized data), the linker can reduce the size of images. Format DZRO_MIN=number-of-pages
1 – Option Values
number-of-pages Specifies the minimum number of contiguous pages. For VAX linking, the linker, by default, uses a minimum of 5 pages. Each VAX page equals 512 bytes. For Alpha linking, the linker, by default, uses a minimum of 1 page. The size of an Alpha page is CPU-specific. The initial set of Alpha systems uses an 8 KB page. The page size used is that of the current link operation. (See the /BPAGE qualifier.) The number of pages must be equal to or greater than the value specified in the parameter.
