A easy question......

I have this line:
for ($i=$#MEMBERS_DATA;$i>=0;$i--) {
But I am not understand it:
what's "=$#"?
Can it write :
for ($i=@MEMBERS_DATA;$i>=0;$i--) {

????

$#MEMBERS_DATA is the index of the last element in the array( first element is 0). This code is processing allelements in the array in reverse order.

You could  say:
for ($i=length(@MEMBERS_DATA)-1;$i>=0;$i--) {

OR
foreach $elem ( reverse @MEMBERS_DATA )
{
   do something with element

#You can write
for ($i=@MEMBERS_DATA-1;$i>=0;$i--){ }  #assuming $[ == 0
#or
for $i ( reverse 0..$#MEMBERS_DATA ){ }

$#Members... is not the last element but the index of the last element.

and length(@MEMBERS_DATA) is not the number of elements in @MEMBERS_DATA but the length of (i.e. the number of digits in) the number of elemens in @MEMBERS_DATA
