Read it yourself in the manual -- if you still have questions after reading the write up and the example in Appendix A, please post them. Principles of Operation

Before SRP was added to 370 architecture, MVO was used primarily (but not exclusively) for shifting packed-decimal data digits, either right or left.

In your example, ABC is shifting itself 4-Bits left, so high-order truncation of the high-order 4-Bits will occur.

As Robert has suggested, a review of the POPS Manual is in order -
