All you need to do is dereference them and do whatever you want with
them.
foreach my $aref (@ARRAY With H strings)
{
my @arr = @$aref;
print ('htapes99', @arr ,5,'true',my %attributes);
}
Of course you will probably want to make a nested loop
to loop thru @arr instead of just printing it.

I was able to get it working without a foreach loop by using:
my @H99tapes = ( ## .. ##);
print $q->scrolling_list(-name=>'imported_tapes',
-values=>[EMAIL PROTECTED],
-default=>[$H99tapes[0]],
-multiple=>1,
-override=>1,
-size=>10),"<br>";
print $q->submit(-name=>'action',-value=>'Delete'),
$q->submit(-name=>'action',-value=>'Add');
##--## Recover the new tape(s) from the Scroll List parameter
'imported_tapes' ##--##
my @imports = param('imported_tapes');
My original problem was I wanted to use splice to dynamically re-populate
an array or hash based off of what the user selected through this scroll
list, but could not get this to work.
Here s the pseucdode I am using:
as H numbers are submitted by user from a scroll list
remove selected elements from @H99tapes
repopulate new list into @UserH99tapes
print @UserH99tapes
OR
as H numbers are submitted by user from a scroll list
remove selected elements from @H99tapes
repush remaining elements into @H99tapes
print @H99tapes
Any ideas to help me with this problem?
basically dynamically splicing an array or hash. Note each element
contains unique data, H[0-1000] strings for example.
##--## BEGIN IMPORT
##--##
##--## AS H NUMBERS ARE SELECTED, REMOVE
SUBMITTED ELEMENTS FROM USER ARRAY ##--##
##--## REPOPULATE LIST INTO NEW ARRAY,
PRINT NEW ARRAY. ##--##
my @tape_imports_to_del =
$q->param(htapes99); ##--## SELECTED BY USER ##--#
my $tape_count = scalar
@tape_imports_to_del; ##--## COUNT ##--##
foreach (@tape_imports)
{
splice
(@H99tapes,0,$tape_count,@H99tapes)
}
thank you,
derek
