what does the K0 (2) and P0 (2) mean in this pattern? I know the k is for knit and P is for purl?

Question

Row 1 *K2, p2; rep from * across row; end k0 (2).
Row 2 P0 (2); *k2, p2, rep from* across row.

Answer 1

Most likely this is referring to an item that has multiple sizes. For the smaller size, you need to k0 at the end (there will be no more stitches on the needle), but for the larger size you must k or p an additional 2 stitches (which you should have cast on at the beginning if doing the larger size).
