I want to thank everyone for helping me, but I am still having trouble. I am trying to get data from a file, like the one below. The 88888 marker means the end of a block. What I am trying to do is have a list of blocks which contain a list of vertices, which contains four elements. I am a little confused on how to read the vertices into the array when I don't know how many there are until I read the file. I apologize if I am repeating myself, but I am still confused. I am using a two dimensional array now and below the data is the code I use to get that. Could I do something like $Block[0] = @datavertex[0];? SO that I can have $Block[0][0][1]

            last VERTEX;
        }

               scalar(<FHV>),

    $vertexcount = $vertexcount + 1;
    chomp @vertex;
    push @datavertex, \ @vertex;
