Yes, ??= is the trigraph for #. Talk about hash!
Trigraphs go away in C++17.
Michael Wong from IBM has already stated that IBM will still support
trigraphs in C++ as an extension. C hasn't deprecated them.
But seeing as #pragma filetag() is already an extension I see no reason
why anybody would use them. I have no idea why
the health checker header files in SYS1.SIEAHDR.H(HZS*) chose to use
them. It's an act of madness!

I have encountered IBM files that used the C++ trigraphs: ??< for { and so
forth. What an unreadable mess! (IMHO, obviously)
I understand that some compilers have a #pragma that disables trigraphs.
Alas, "#" may not be entirely portable and may need to be coded as a
trigraph.
