`my @input = ({},{})` just creates an array containing two empty hash references which are going to be filled later. The input data can be passed directory to STDIN of the script or stated as a command line argument (`<>` is a special case, input from `<>` comes either from standard input, or from each file listed on the command line. See I/O Operators). Sorry if my advice was wrong.	[reply] [d/l] [select]
