Re: The process cannot access the file because it is being used by another process?

Another process is accessing the DATA pseudo-handle?

There's an answer on SO pointing out that it doesn't have to be a different process. I don't know if there's anything in that answer that would prove helpful.

I can't reproduce your problem, btw.
I generated a test file thusly:

use warnings;

open WR, '>', 'buk.pl' or die $!;

print WR
 "#! perl -slw\n",
 "use strict;\n\n",
 "my \@data;\n",
 "my \$i = 0;\n\n",
 "#\$data[ \$i++ ] = [ split ' ' ]\n\n",
 "++\$i while <DATA>;\n\n",
 "print \$i;\n\n",
 "__DATA__\n\n";

for(1 .. 500000) {
  print WR
  "-69.282032302755084 40.000000000000014  0   -1\n",
  "-69.123493781255831 39.908467741935496  -1.4443382565142906e-006   
+ -1\n",
  "-68.748013135538145 40.911009397420145  0   -1\n",
  "-68.964955259756593 39.816935483870985  -2.990721348858345e-006 -1\
+n",
  "-68.370049396495517 40.298149116372635  -6.3944096502804299e-006   
+ -1\n",
  "-68.202015544462682 41.814890597403163  0   -1\n";
}

And then ran the generated perl script (on 32-bit perl-5.16.0 and 64-bit perl-5.22.0), Windows 7:

C:\_32\pscrpt>perl buk.pl
3000001
