216 Appendix C: Memory Allocation
1. Place dd, the number of the highest data storage register you want
allocated, into the display. 1 dd 97. The number of registers in
the uncommitted pool (and therefore potentially available for
programming) will be (97 − dd).
2. Press ´ m %.
There are two ways to review your allocation:
Press l m % to recall into the stack the number of the
highest-allocated data storage register, dd. (Programmable.)
Press | W (as explained above) to view a more complete
memory status (dd uu ppb).

Restrictions on Reallocation
Continuous Memory will maintain the configuration you allocate until a
new m % is executed or Continuous Memory is reset. If you try to
allocate a number less than 1, dd = 1. If you try to allocate a number
greater than 97,

If program memory is not cleared, the number of uncommitted registers (uu) is less,
owing to allocation of registers to program memory (pp). Therefore, pp would be > 0 and
b would vary.
