So are the defaults the same or not?
If they are you can do something like
while (<FILE>) {
my($file1,$file2,$file3,$file4,$file5,$file6,$file10,$file25,$file27)
= (split( /\|/, $_))[3,4,6,7,12,40,41,42,43,46,56,64];
for($file1,$file2,$file3,$file4,$file5,$file6,$file10,$file25,$file27)
{
$_ |= 'default';
}
}
Actually this seems to work as well:
while (<FILE>) {
$_ |= 'default' for
(my($file1,$file2,$file3,$file4,$file5,$file6,$file10,$file25,$file27)
= (split( /\|/, $_))[3,4,6,7,12,40,41,42,43,46,56,64]);
# and some code using $file1, ...
}
If you want a different default for each field, you can't IMHO do
better than the original code.
