Why doesn't COFF format support ALIGN larger than 4? Any particular reason?

IIRC, 2^13 alignment is possible? Are we talking file alignment, section alignment? Can you give an example?

I meant larger than 4. Sorry.

FASM complains "section not align enough" both in code and data if I used "ALIGN 8". I meant that directive ALIGN.

I want to know whether it is a COFF / COFF64 -bound specification or something from FASM.

ALIGN bases it's limitations on the section alignment to insure granularity is actually possible. So, I would assume you've not aligned the section sufficiently.

Only the Microsoft extensions to COFF format (the "MS COFF" as it is called in fasm) support custom alignments of sections.

Thanks for clearing that up people. I forgot that a section can be tagged with ALIGN.
