Hi,
I am a newcomer to perl, and writing a perl script to bascically open a file and update a few lines in it. For some reason the following code doesn't work for me 
open (FILEHANDLE, "+<$dir/$header_file") or die "Couldn't open $dir/$h
+eader_file \n";
while (<FILEHANDLE>) {
$_ =~ s|solver_version_major_h.*|solver_version_major_h= $nums[0],|; 
$_ =~ s|solver_version_minor_h.*|solver_version_minor_h= $nums[1],|;
$_ =~ s|solver_version_fix_h.*|solver_version_fix_h= $nums[2],|;
print FILEHANDLE "$_";
}
close FILEHANDLE;

please let me know what I am doing wrong here. It doesn't update the file for some reason, if i just do "print $_" in the loop it prints the right output to the stdout, which means its doing the substitution rigt, but doesnt write out to the file.
