It may not be.

Right. The compiler could produce something like:
$tmp1 = $index + 1
$tmp2 = $tmp1 % $asize
$index = $tmp2
$index = $tmp1

Not that strange for compilers which produce code for real CPUs (which
often have very strange timing requirements). I wouldn't really expect
it from a simple bytecode-generating compiler like perl's.
The warning that the execution order is undefined comes from C. But in C
this is a consequence of the concept of "sequence points". The language
defines certain points (e.g., the end of each statement, each function
call, etc.) where each previous operation must be finished and no
subsequent operation must have begun. between two sequence points the
compiler can reorder operations at will. There are two rules about
modifying values:
1) You can modify an object[1] only once between two sequence points
2) If you modify an object, you can only read it to compute the new
value.
But Perl doesn't have the concept of sequence points, and there is no
general prohibition agains modifying the same object twice in a
statement, just against using the increment and decrement operators.
That does stand out as an odd exception. IMHO Perl should either define
an execution order (which could be a partial order) or adopt a more
generic concept like that of C.

Surprisingly,
$index = ++$index % $asize;
is really about 40 % faster than
$index = ( $index + 1 ) % $asize;
I had not expected this. Apparently creating a constant IV is a
relatively expensive operation (well, it takes about 36 nanoseconds on
my PC, so "relatively expensive" is, er, relative).

I have roughly 350 million lines of data in the following form

Is there some kind of sane way to sort this without taking up too much

Looks good, except for missing '. "\n"' at the end of last line.

Why "die" when there is no error? Better "exit (0)".

I have a Windows Xp and use Strawberry the think is the hello word

I do "perl filename.pl" in the command line and it gives a error

As with any other command, the path to it must be in the Windows search
path. Can you execute the program with the full path to perl?

The actual Strawberry 5.10.x (exe-installer) version
puts itself into %SystemDrive%\strawberry\perl\bin and
adds two locations to the Windows path (e.g., if the
system drive is C):
C:\strawberry\perl\bin;C:\strawberry\c\bin;
During the install, there is no option to
modify or to skip that step. Maybe there's
only a reboot of the Windows XP required.

A reboot should not be necessary but changes in environment variables will
not be propagated to already open cmd.exe windows.
Out of curiosity, I downloaded Strawberry Perl. I was a little
disappointed that it would not let me install in a different location (I
put certain stuff in c:\opt to avoid paths with spaces) but I guess I
could live with that.
The installer put
C:\strawberry\perl\bin;C:\strawberry\c\bin;
at the end of %PATH%. Well, that is not going to work for me (I have quite
a few Perl installations at the moment). So, I fired up a cmd prompt:
C:\Temp> set PATH=C:\strawberry\c\bin;C:\strawberry\perl\bin;%path%
C:\Temp> perl -V
...
Built under MSWin32
Compiled at Apr 17 2008 11:36:20
@INC:
C:/strawberry/perl/lib
C:/strawberry/perl/site/lib
.
It looks like I am set.
C:\Temp> perl -e "print qq{Hello World\n}"
Hello World
Indeed.
Even my scripts using Win32::OLE work.
Conclusion: The OP's problem seems to be either one of two things:
1) Possible interference with the installation process. Not likely unless
he really went out of his way.
2) Trying to run perl from the same cmd shell used to initiate
installation. In this case, the solution is to start up a new shell.

Then perl.exe is not in your search path.

Add perl.exe (actually the directory that contains perl.exe) to your
search path or use a fully qualified path to access perl.exe

Yes - that's one of the things I would like to see fixed in
Strawberry. However, if you wanted, it's not such a big deal to
relocate it.
Just copy the whole lot over to c:\wherever and then replace (in
Config.pm and Config_heavy.pl) every occurrence of c:\strawberry with
c:\wherever.
Then amend the path settings appropriately and you should be done.
Cheers,
Rob

Thank you. I should have checked that myself. I am hoping that the OP
dropped the use of "OFP$k" in favor of $OFP[$k].
