Yes, sorry. The correct URL is http://www.tachyonsoft.com/cpindex.htm

The list of "variant" characters in the C/C++ Programming Guide is
certainly consistent with the code pages that I have researched.
I was surprised to see / in your original list because it is one
of the base-64 characters and it was specificly chosen because it
is invariant for all ASCII and EBCDIC code pages.  I have not seen
& ' - / < > or ? remapped in any EBCDIC code page, so I don't know
why they were included in your original list.

There are far more than 13 variant EBCDIC characters.  The list
may be those characters that are invariant in ASCII but variant
in EBCDIC.

The fact that the brackets are variant in EBCDIC causes no end of
problems when coding and interpreting C source and XML documents.
