Version 5.003_25

If your prefix contains the string "perl", then the directories
are simplified. For example, if you use prefix=/opt/perl,
then Configure will suggest /opt/perl/lib instead of
-/usr/local/lib/perl5/.
+/opt/perl/lib/perl5/.
By default, Configure will compile perl to use dynamic loading, if
your system supports it. If you want to force perl to be compiled

symbolic links (if they are supported). It can be used
in the Makefile. It is either 'ln -s' or 'ln'
+longsize (intsize.U):
+ This variable contains the value of the LONGSIZE symbol,
+ which indicates to the C program how many bytes there are
+ in a long integer.
+
lseektype (lseektype.U):
This variable defines lseektype to be something like off_t, long,
or whatever type is used to declare lseek offset's type in the
This symbol contains the type of pointer returned by shmat().
It can be 'void *' or 'char *'.
+shortsize (intsize.U):
+ This variable contains the value of the SHORTSIZE symbol,
+ which indicates to the C program how many bytes there are
+ in a short integer.

shrpenv (libperl.U):
If the user builds a shared libperl.so, then we need to tell the
'perl' executable where it will be able to find the installed libperl.so.

+=item Illegal character %s (carriage return)
+
+(F) A carriage return character was found in the input. This is an
+error, and not a warning, because carriage return characters can break
+here documents (e.g. C<print E<LT>E<LT>EOF;>). Note that Perl always
+opens scripts in text mode, so this error should only occur in C<eval>.

system call to call, silly dilly.
-=item Too late for "-T" option (try putting it first)
+=item Too late for "B<-T>" option (try putting it first)
(X) The #! line in a Perl script contains the "-T" option, but Perl
was not invoked with "-T" in its argument list. Due to the way Perl
the F<.ph> files made by B<h2ph> will probably end up as extension modules
made by B<h2xs>. (Some F<.ph> values may already be available through the
POSIX module.) The B<pl2pm> file in the distribution may help in your
-conversion, but it's just a mechanical process, so is far from bulletproof.

+=item backticks
+
+Backticks create a subprocess, and pass the enclosed string
+to it for execution as a DCL command. Since the subprocess is
+created directly via C<lib$spawn()>, any valid DCL command string
+may be specified.
+
=item binmode FILEHANDLE
The C<binmode> operator will attempt to insure that no translation
Also, negative signal values don't do anything special under
VMS; they're just converted to the corresponding positive value.
+=item qx//
+
+See the entry on C<backticks> above.
+
=item select (system call)
If Perl was not built with socket support, the system call
of the empty string, C<system> spawns an interactive DCL subprocess,
in the same fashion as typiing B<SPAWN> at the DCL prompt.
Perl waits for the subprocess to complete before continuing
-execution in the current process.
+execution in the current process. As described in L<perlfunc>,
+the return value of C<system> is a fake "status" which follows
+POSIX semantics; see the description of C<$?> in this document
+for more detail. The actual VMS exit status of the subprocess
+is available in C<$^S> (as long as you haven't used another Perl
+function that resets C<$?> and C<$^S> in the meantime).
=item time
were entirely uppercase, regardless of the case actually
specified in the Perl expression.
-=item $?
-
-Since VMS status values are 32 bits wide, the value of C<$?>
-is simply the final status value of the last subprocess to
-complete. This differs from the behavior of C<$?> under Unix,
-and under VMS' POSIX environment, in that the low-order 8 bits
-of C<$?> do not specify whether the process terminated normally
-or due to a signal, and you do not need to shift C<$?> 8 bits
-to the right in order to find the process' exit status.
-
=item $!
The string value of C<$!> is that returned by the CRTL's
corresponding VMS message string, as retrieved by sys$getmsg().
Setting C<$^E> sets vaxc$errno to the value specified.
+=item $?
+
+The "status value" returned in C<$?> is synthesized from the
+actual exit status of the subprocess in a way that approximates
+POSIX wait(5) semantics, in order to allow Perl programs to
+portably test for successful completion of subprocesses. The
+low order 8 bits of C<$?> are always 0 under VMS, since the
+termination status of a process may or may not have been
+generated by an exception. The next 8 bits are derived from
+severity portion of the subprocess' exit status: if the
+severity was success or informational, these bits are all 0;
+otherwise, they contain the severity value shifted left one bit.
+As a result, C<$?> will always be zero if the subprocess' exit
+status indicated successful completion, and non-zero if a
+warning or error occurred. The actual VMS exit status may
+be found in C<$^S> (q.v.).
+
+=item $^S
+
+Under VMS, this is the 32-bit VMS status value returned by the
+last subprocess to complete. Unlink C<$?>, no manipulation
+is done to make this look like a POSIX wait(5) value, so it
+may be treated as a normal VMS status value.
