in reply to Making an array of predifined length with default values

my @array = (0) x 1000;

[download]

Even works with lists of arbitrary length, such as my @array = (1, 2, 3) x 100;  (which creates 300 elements).

(but memory-wise, it's not better than iteratively filling the elements, maybe even with predeclaring some initial max size with $#array = 1000; to avoid successive automatic resizing...)

    Just a very minor nit: the statement  $#array = 1000; sets the maximum array index to 1000 and so predeclares an array with 1001 elements (assuming $[ == 0; see perlvar).

    Thanks, this works perfectly! I though it only worked for strings. Thanks again
