thanks for the solution... it solves my delimma about array slice referencing. but i want something to clarify about your codes (as follows):

my @ref = ([\@array[2,0]],[\@array[1]]);
[download]

does this mean (logic flow):

(1) to create a reference for the array slice (2) assign that reference to the newly created anonymous array (3)assign the refernce of the anonymous array to the list values of @ref

was this right? so it means we have to create an extra one reference (memory address) to every list values of @ref?

im just curious, how much is the size (in bytes) of a reference? since a reference consumes a space of memory in which the memory address of one variable is its value...
