Query: Excellent for my needs...to further understand internals

This is an excellent book with good examples for a entry/junior level assembler programmer. The approach is unique in that the focus is on the instructions at the basic level. Each level is progressively expanded. Being a Cobol programmer, the book broadened my understanding of computer internals. I also have the Stern Cobol manual which is excellent and productivity oriented.
