+
+EBCDIC Perl is still a work in progress. All the core code works as far as we
+know, but various modules you might want to download from CPAN do not. The
+failures range from very minor to catastrophic. Many of them are simply bugs
+in the tests, with the module actually working properly. This happens because,
+for example, the test is coded to expect a certain character ASCII code point;
+when it gets the EBCDIC value back instead, it complains. But the code
+actually worked. Other potential failures that aren't really failures stem
+from checksums coming out differently, since C<A>, for example, has a different
+bit representation between the character sets. A test that is expecting the
+ASCII value will show failure, even if the module is working perfectly. Also
+in sorting, uppercase letters come before lowercase letters on ASCII systems;
+the reverse on EBCDIC.
+
+Some CPAN modules come bundled with the downloaded perl. And a few of those
+have yet to be fixed to pass on EBCDIC platforms. As a result they are skipped
+when you run 'make test'. The current list is:
+
+ Archive::Tar
+ Config::Perl::V
+ CPAN::Meta
+ CPAN::Meta::YAML
+ Digest::MD5
+ Digest::SHA
+ Encode
+ ExtUtils::MakeMaker
+ ExtUtils::Manifest

+ Pod::Simple
+ Socket
+ Test::Harness
