Tracking which elements from an array have been matched.

Hello
I have an array of records. I need to search this array for a
particular record (or records) based on a record id.
This is simple enough (e.g. using the grep function)
@found = grep {/$rec_id/} @array;
However, I also need to keep a track of which records in the array have
been 'found' (so I can later identify any records that haven't).
This would be pretty simple with a loop, something like:
for ($i=0; $i < @data; $i++)
{
if ($array[$i] =~ /$rec_id/)
{
push (@found, $array[$i]) ;
$found_recs{$i} = "TRUE";
}
}
But this seems quite inefficient, and I'm sure there must be a better
way of doing this. This is part of a larger script that is becoming
quite large so I'm trying to be more efficient (and to improve my
coding).
Can anyone offer any suggestions.
Cheers
Andy Taylor
