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.
