Hello all,

I have started working on my first real project, to send reminder emails out when meetings are due. Ultimately I want to read a text file (prev.txt) which consists of lines with 9 entries into an array, for each set of 9 entries process them and send emails as necessary, then write the amended array to a file again.

After an earlier query I have altered my first snippet of code as below and put the print command in to test what I have got but it doesn't work. If I replace the 2 with 0 I get what looks like the first line of the data file printed but I expected to get just the first item, 31307MWB using the example below.

A line of data looks like:-

31307MWB name@address name@address name@address 10 11 103 90 0

Can someone tell me what I am doing wrong?

TIA S. 

#!/usr/bin/perl -w
use strict;

my(@DATAFILE);

@DATAFILE=&readdata();
print $DATAFILE[2];
&writedata(@DATAFILE);

#
# Subroutine for reading prev.txt into an array
#

sub readdata {
    open (PH, "prev.txt") || die "Cannot open prev.txt: $!";
    my(@DATA)=<PH>;
    chomp @DATA;
    close (PH);
    return(@DATA);
}

#
# Subroutine for writing array into prev.txt
#

sub writedata {
    my(@DATA)=@_;
    open (PH, ">prev.txt") || die "Cannot open prev.txt: $!";
    foreach(@DATA) {
        print PH "$_\n";
    }
    close (PH);
}
