a non-denominational season's greeting to everyone,
I've downloaded and installed sybperl and am experiencing a perl crash when running one of the sample programs.  The message I get is an OK dialogue with the following:
    "Perl.lexe has generated errors and will be closed by ...

"The Perl DBI Database Driver Writer's Guide" introduces attribute
handling in the following way:
  Note the use of the STORE method for setting the dbh attributes.
  That's because within the driver code, the handle object you have is

"The Perl DBI Database Driver Writer's Guide" mentions
table_info() and type_info_all() as "Other statement

There use to be a rather lengthy FAQ on how to use sybperl but can not find

I am thinking of extending the DBD::AnyData DSN in three ways and would

Dear Tim,
I was just getting ready to ship DBD::Informix 2004.02 when I made the
mistake of testing it with Perl 5.6.1 and DBI 1.46.
I ran into problems with a DBD::Informix test that was expecting an error

DBI::DBD informs us that
  The DBI Driver.xst code will call dbd_st_finish for you, if the
  sth has the ACTIVE flag set, before calling dbd_st_destroy.
However, a pure perl DBD doesn't operate in such a luxurious

As mod_perl 2 is going to be released shortly the issue with DBI and
friends not being thread-safe (I believe DBI is fine, but DBDs are not)
becomes a problem. Since Apache 2 has a bunch of threaded MPM
implementations and while Unix users could always use prefork MPM (no
