Alteration of Register Contents
Whenever you change the current word size, the contents of the
stack are affected (as explained under Word Size in section 3), while
those of the storage registers are not. However, a change in word
size does change the size and boundaries (and total number) of the
storage registers. This can make a specific set of stored bits
inaccessible in its original form—until you restore the original
word size. Therefore, you can temporarily change the word size (for
instance, for a calculation), and still recover your stored data when
you return to the original word size.
Example: The following sequence illustrates what happens to
data stored in R; and R, when the word size is doubled (from 16 to
32) and then restored to its original size.
