139 original intent was that I32 be *exactly* 32 bits.
140
141 Currently, we only guarantee that I32 is *at least* 32 bits.
142 Specifically, if int is 64 bits, then so is I32. (This is the case
143 for the Cray.) This has the advantage of meshing nicely with
144 standard library calls (where we pass an I32 and the library is
145 expecting an int), but the disadvantage that an I32 is not 32 bits.

476=head1 Character classes
8a58bdcf
KW		 477There are three variants for all the functions in this section. The base ones
478operate using the character set of the platform Perl is running on. The ones
479with an C<_A> suffix operate on the ASCII character set, and the ones with an
480C<_L1> suffix operate on the full Latin1 character set. All are unaffected by
181ab5fd 481locale and by C<use bytes>.
8a58bdcf
KW		 482
483For ASCII platforms, the base function with no suffix and the one with the
484C<_A> suffix are identical. The function with the C<_L1> suffix imposes the
485Latin-1 character set onto the platform. That is, the code points that are
486ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII
487code points are treated as if they are Latin-1 characters. For example,
488C<isSPACE_L1()> will return true when called with the code point 0xA0, which is
489the Latin-1 NO-BREAK SPACE.
490
491For EBCDIC platforms, the base function with no suffix and the one with the
492C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code
493pages that Perl knows about all are equivalent to Latin-1. The function that
494ends in an C<_A> suffix will not return true unless the specified character also
495has an ASCII equivalent.

506character corresponds to an ASCII character. Variants C<isASCII_A()> and

542C<isALNUM()> is a synonym provided for backward compatibility. Note that it

JC		 1064In 5.9.3, Newx() and friends replace the older New() API, and drops
1065the first parameter, I<x>, a debug aid which allowed callers to identify
37b8b4c9 1066themselves. This aid has been superseded by a new build option,
d10b4965 1067PERL_MEM_LOG (see L<perlhacktips/PERL_MEM_LOG>). The older API is still
