i think i know what your asking and if that is the case this is what is happening.
line 1 says read each line in the file.
line 3 says for each space add a new element to @ar for each items read in $_. (IE: for the first line read in @ar=qw(1 2 3 4)
line 7 says for each entry to @ar create an anonymous array inside @multiarray. (IE:
@mulriarray=(
[1,2,3,4];
);
)
if you are trying to do something else be as detailed in your question as possable and i am sure we can get you sorted out and pointing in the right direction.
