Hello all,

I have a CGI app. that stores data in a text file of format:

--Start of file
FIELD1: VALUE1
FIELD2: VALUE2
FIELD3: VALUE3
FIELD4: VALUE4
/n
FIELD1: VALUE1
...and so on

Note: FIELD1 is unique, others aren't

My program reads this file and stores the data in an array, and saves it back 
as a text file when data has been changed. I am able to add new data, but not 
remove it. I'm not sure how to go about it as I need to remove all four 
fields for a unique record.

Here's the code for reading in the records and placing it into an array. Some 
of you may recognise it as it's straight out of the Perl Cookbook:

open( FILE, "records.dat" ) or die "Can't open record file: $!";
$/ = "";                # paragraph read mode
while (<FILE>)
{
    my @fields = split /^([^:]+):\s*/m;
    shift @fields;      # for leading null field
    push(@Array_of_Records, { map /(.*)/, @fields });
}

Since I'm still learning Perl and CGI I don't wholly understand this snippet.

Any help (especially a walkthrough of what's going on and why) would be very 
much appreciated.

Geraint.
