If so, what is used to separate the fields?
Here is an example where the fields are separated with a '|' character.
Assume you want the first field to be "Person" and the third field to be "Every month":
$Record0Search = "Person";
$Record2Search = "Every month";
open(FILE, "data.txt");
while ($Line = <FILE>) {
@Fields = split '\|', $Line;
print $Line if (($Fields[0] eq $Record0Search) && ($Fields[2] eq $Record2Search));
}
