Fellow monks,
I have a new quandary, here it is:
.... loop ....
@array = ($refnum, $scalar);
push @chunk, @array;
print "@array\n";
$refnum++;
next;
}
warn "\ndebugging: @chunk\n";
print "delete?: ";
chomp (my $number = <STDIN>);
delete ($chunk[$number]);
open (TO_WRITE, ">$ARGV[0]");
while (<TO_WRITE>) {
print TO_WRITE @chunk;
}
The basic idea is, the script should open a file, extract certain fragments of data (lets pretend these 'certain fragments' are $scalar), then the user can choose which $scalar to delete from the file; then delete it.
The problem in this script, is that it is (I think) deleting all the elements of the array, and then writing to the file.
Please help :)
