A point is that while the array is called @groceries<\/span>, a single element in the array is referenced using $groceries[index]<\/span>. For example, the zeroth element is referenced by $groceries[0]<\/span>. The dollar sign is used to reference a single element in the array.<\/em><\/p>\n Another point, which is just a reminder, is that Perl arrays start at position 0. Therefore, the third element in @groceries is $groceries[2]. Perl sees it as $groceries[0], $groceries[1], $groceries[2]….<\/p>\n My compiler seems rather relaxed about whether I use $groceries[2] or @groceries[2] to reference the third element in the array. However, everywhere I read says to reference a single array element with $array[index] rather than @array[index]; I guess we will.<\/p>\n HTH & HNY:)<\/p>\n Sources:<\/p>\n Robert’s Perl tutorial<\/a><\/p>\n McGrath, Mike.

\nBack in my Oct 4<\/a> post, I introduced a Perl program that searches a grocery list for olive oil. The items in the list are stored in an array; the program checks the items one by one to see if that particular item is olive oil.<\/p>\n
