(F) The "use" keyword is recognized and executed at compile time, and returns
no useful value. See L<perlmod>.
+=item '!' allowed only after types %s
+
+(F) The '!' is allowed in pack() and unpack() only after certain types.
+See L<perlfunc/pack>.
+
=item % may only be used in unpack
(F) You can't pack a string by supplying a checksum, because the
checksumming process loses information, and you can't go the other
way. See L<perlfunc/unpack>.
+=item /%s/: Unrecognized escape \\%c passed through
+
+(W) You used a backslash-character combination which is not recognized
+by Perl. This combination appears in an interpolated variable or a
+C<'>-delimited regular expression.
+
=item %s (...) interpreted as function
(W) You've run afoul of the rule that says that any list operator followed
instead of Perl. Check the #! line, or manually feed your script
into Perl yourself.
+=item (in cleanup) %s
+
+(W) This prefix usually indicates that a DESTROY() method raised
+the indicated exception. Since destructors are usually called by
+the system at arbitrary points during execution, and often a vast
+number of times, the warning is issued only once for any number
+of failures that would otherwise result in the same message being
+repeated.
+
+Failure of user callbacks dispatched using the C<G_KEEPERR> flag
+could also result in this warning. See L<perlcall/G_KEEPERR>.

(F) With "strict subs" in use, a bareword is only allowed as a
-subroutine identifier, in curly braces or to the left of the "=>" symbol.
+subroutine identifier, in curly brackets or to the left of the "=>" symbol.
Perhaps you need to predeclare a subroutine?
=item Bareword "%s" refers to nonexistent package
(P) Perl detected an attempt to copy an internal value that is not copiable.
+=item Buffer overflow in prime_env_iter: %s
+
+(W) A warning peculiar to VMS. While Perl was preparing to iterate over
+%ENV, it encountered a logical name or symbol definition which was too long,
+so it was truncated to the string shown.
+
=item Callback called exit
(F) A subroutine invoked from an external package via perl_call_sv()
usually double the curlies to get the same effect though, because the inner
curlies will be considered a block that loops once. See L<perlfunc/next>.
+=item Can't read CRTL environ
+
+(S) A warning peculiar to VMS. Perl tried to read an element of %ENV
+from the CRTL's internal environment array and discovered the array was
+missing. You need to figure out where your CRTL misplaced its environ
+or define F<PERL_ENV_TABLES> (see L<perlvms>) so that environ is not searched.
+
=item Can't "redo" outside a block
(F) A "redo" statement was executed to restart the current block, but
(F) You called C<perl -x/foo/bar>, but C</foo/bar> is not a directory
that you can chdir to, possibly because it doesn't exist.
+=item Can't check filesystem of script "%s"
+
+(P) For some reason you can't check the filesystem of the script for nosuid.
+
=item Can't coerce %s to integer in %s
(F) Certain types of SVs, in particular real symbol table entries
Either qualify the sort variable with the package name, or rename the
lexical variable.
+=item Bad evalled substitution pattern
+
+(F) You've used the /e switch to evaluate the replacement for a
+substitution, but perl found a syntax error in the code to evaluate,
+most likely an unexpected right brace '}'.
+
=item Can't use %s for loop variable
(F) Only a simple scalar variable may be used as a loop variable on a foreach.
(W) You tried to do a connect on a closed socket. Did you forget to check
the return value of your socket() call? See L<perlfunc/connect>.
+=item Constant is not %s reference
+
+(F) A constant value (perhaps declared using the C<use constant> pragma)
+is being dereferenced, but it amounts to the wrong type of reference. The
+message indicates the type of reference that was expected. This usually
+indicates a syntax error in dereferencing the constant value.
+See L<perlsub/"Constant Functions"> and L<constant>.

=item Constant subroutine %s redefined
(S) You redefined a subroutine which had previously been eligible for

+(F) While under the C<use filetest> pragma, switching the real and
+effective uids or gids failed.

=item Error converting file specification %s
(F) An error peculiar to VMS. Because Perl may have to deal with file
(W) You are blessing a reference to a zero length string. This has
the effect of blessing the reference into the package main. This is
usually not what you want. Consider providing a default target

versions of Perl are likely to eliminate these arbitrary limitations.
-=item Ill-formed logical name |%s| in prime_env_iter
+=item Ill-formed CRTL environ value "%s"
-(W) A warning peculiar to VMS. A logical name was encountered when preparing
-to iterate over %ENV which violates the syntactic rules governing logical
-names. Because it cannot be translated normally, it is skipped, and will not
-appear in %ENV. This may be a benign occurrence, as some software packages
-might directly modify logical name tables and introduce nonstandard names,
-or it may indicate that a logical name table has been corrupted.
+(W) A warning peculiar to VMS. Perl tried to read the CRTL's internal
+environ array, and encountered an element without the C<=> delimiter
+used to spearate keys from values. The element is ignored.
+
+=item Ill-formed message in prime_env_iter: |%s|
+
+(W) A warning peculiar to VMS. Perl tried to read a logical name
+or CLI symbol definition when preparing to iterate over %ENV, and
+didn't see the expected delimiter between key and value, so the
+line was ignored.
=item Illegal character %s (carriage return)
(F) You tried to divide a number by 0 to get the remainder. Most numbers
don't take to this kindly.
-=item Illegal octal digit
+=item Illegal binary digit %s

+to a floating point representation internally--subject to loss of
+precision errors in subsequent operations--so this limit usually
+doesn't apply to decimal literals.

whether the current call to C<exec> should affect the current

+=item glob failed (%s)
-(P) Something went wrong with the external program(s) used for C<glob>

+(W) Something went wrong with the external program(s) used for C<glob>
+and C<E<lt>*.cE<gt>>. Usually, this means that you supplied a C<glob>
+pattern that caused the external program to fail and exit with a nonzero
+status. If the message indicates that the abnormal exit resulted in a

=item listen() on closed fd
(W) You tried to do a listen on a closed socket. Did you forget to check
(F) While certain functions allow you to specify a filehandle or an
"indirect object" before the argument list, this ain't one of them.
+=item Missing command in piped open
+
+(W) You used the C<open(FH, "| command")> or C<open(FH, "command |")>
+construction, but the command was missing or blank.

=item Missing operator before %s?
(S) This is an educated guess made in conjunction with the message "%s
found where operator expected". Often the missing operator is a comma.
-=item Missing right bracket
+=item Missing right curly or square bracket
-(F) The lexer counted more opening curly brackets (braces) than closing ones.

=item panic: last
(P) We popped the context stack to a block context, and then discovered
(P) A "can't happen" error, because safemalloc() should have caught it earlier.
-=item regexp too big
-
-(F) The current implementation of regular expressions uses shorts as
-address offsets within a string. Unfortunately this means that if
-the regular expression compiles to longer than 32767, it'll blow up.
-Usually when you want a regular expression this big, there is a better
-way to do it with multiple statements. See L<perlre>.

(F) You tried to assign to C<$)>, and your operating system doesn't support
which does return. To suppress this warning, put the exec() in a block
by itself.
+=item Strange *+?{} on zero-length expression
+
+(W) You applied a regular expression quantifier in a place where it
+makes no sense, such as on a zero-width assertion.
+Try putting the quantifier inside the assertion instead. For example,
+the way to match "abc" provided that it is followed by three
+repetitions of "xyz" is C</abc(?=(?:xyz){3})/>, not C</abc(?=xyz){3}/>.

=item Stub found while resolving method `%s' overloading `%s' in package `%s'
(P) Overloading resolution over @ISA tree may be broken by importation stubs.
(F) Your Perl was compiled with B<-D>SETUID_SCRIPTS_ARE_SECURE_NOW, but a
version of the setuid emulator somehow got run anyway.
+=item switching effective %s is not implemented
+
+(F) While under the C<use filetest> pragma, we cannot switch the
+real and effective uids or gids.
+
=item syntax error
(F) Probably means you had a syntax error. Common reasons include:
if the last stat that wrote to the stat buffer already went past
the symlink to get to the real file. Use an actual filename instead.
+=item This Perl can't reset CRTL eviron elements (%s)
+
+=item This Perl can't set CRTL environ elements (%s=%s)
+
+(W) Warnings peculiar to VMS. You tried to change or delete an element
+of the CRTL's internal environ array, but your copy of Perl wasn't
+built with a CRTL that contained the setenv() function. You'll need to
+rebuild Perl with a CRTL that does, or redefine F<PERL_ENV_TABLES> (see
+L<perlvms>) so that the environ array isn't the target of the change to
+%ENV which produced the warning.

=item times not implemented
(F) Your version of the C library apparently doesn't do times(). I suspect
(F) There are no byte-swapping functions for a machine with this byte order.
+=item Unknown process %x sent message to prime_env_iter: %s
+
+(P) An error peculiar to VMS. Perl was reading values for %ENV before
+iterating over it, and someone else stuck a message in the stream of
+data Perl expected. Someone's very confused, or perhaps trying to
+subvert Perl's population of %ENV for nefarious purposes.

=item unmatched () in regexp
(F) Unbackslashed parentheses must always be balanced in regular
expressions. If you're a vi user, the % key is valuable for finding
the matching parenthesis. See L<perlre>.
-=item Unmatched right bracket
+=item Unmatched right %s bracket
-(F) The lexer counted more closing curly brackets (braces) than opening

-=item Use of "$$<digit>" to mean "${$}<digit>" is deprecated
-
-(D) Perl versions before 5.004 misinterpreted any type marker followed
-by "$" and a digit. For example, "$$0" was incorrectly taken to mean
-"${$}0" instead of "${$0}". This bug is (mostly) fixed in Perl 5.004.
-
-However, the developers of Perl 5.004 could not fix this bug completely,
-because at least two widely-used modules depend on the old meaning of
-"$$0" in a string. So Perl 5.004 still interprets "$$<digit>" in the
-old (broken) way inside strings; but it generates this message as a
-warning. And in Perl 5.005, this special treatment will cease.
-
=item Use of $# is deprecated
(D) This was an ill-advised attempt to emulate a poorly defined B<awk> feature.

+
+(W) A warning peculiar to VMS. Perl tried to read the value of an %ENV
