reverse data read.
Basically I am reading data in from a flat-file that looks like this: (format like $itemid|$reportdate|)
0|10/1/1998|
1|11/08/1998|
2|11/10/1998|
3|11/25/1998|
4|12/01/1998|
5|12/05/1998|
6|12/6/1998|
7|1111|
using code like this:
open(adb,$resourcedb);
while (<adb>) {
open (AFILE,"$resourcedb") || die "Content-type: text/html\n\nCan't Open $resourcedb(r): $!\n";
@LINES=<AFILE>;
close(AFILE);
$SIZE=@LINES;
for ($i=0;$i<=$SIZE;$i++) {
$_=$LINES[$i];
($itemid, $reportdate) = split(/\|/,$_);
print "<A HREF=\"reports/$itemid\">$
}
close(adb);
}
BUT - I don't want to read/print from top down, I would prefer it be in reverse order i.e. reading/printing the last record (record 7) first then going back to record 0 - any easy way to do this off the top of your head?

($itemid, $reportdate) = split/\|/;
print qq?<A HREF="reports/$itemid">$re
}
#but why are you doing this looping over each line of <adb>?
