216 Appendix C: Memory Allocation
1.
Place dd, the number of the highest data storage register you want
allocated, into the display. 1dd65. The number of registers in the
uncommitted pool (and therefore potentially available for
programming) will be (65  dd).
2.
Press ´ m %.
There are two ways to review your allocation:
 Press lm % 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 pp-b).

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 65, Error 10 results.
*
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.
