Hi, I'm not sure if "row" is the right word, but I'm trying to work out how to remove a row from a 2Darray based on a match. I've attempted with the following code, although it doesn't work, as the array "shifts" as I remove "rows". I assume I am going about this the wrong way, so any help would be appreciated. I dont want to just blank the row, I want to remove it completely from the array. The array in real life is about 10k rows, and the match criteria would be a variable.


@arr=(['a','b','c','d'],['e','f','g'],['h','i','j'],['e','f','g'],['h'
+,'i','j'],['e','f','g'],['h','i','j'],['a','b','c','d'],['a','b','c',
+'d']);
@arr1 = @arr;
for(@arr){print @$_, ":";}
print "\n";
$i=-1;
for(@arr){
$i++;
print "i = $i\n";
                if(@$_[0] =~ /e/){
                        splice(@arr1,$i,1);
                }
}
for(@arr1){print @$_, ":";}
print "\n";

The desired outcome of the above would be: @arr=('a','b','c','d','h','i','j','h','i','j','h','i','j','a','b','c','d','a','b','c','d')
