8.5 Memory Operations.
There are 10 separate memories for storing conversion factors, partial results, etc. They are
numbered 0 to 9. The commands for memory number 1, for example, are as follows:
Clear memory 1: press SPACE with K, then 1.
Store number in memory 1: press SPACE with S, then 1.
Add to memory 1: press SPACE with A, then 1.
Recall contents of memory 1: press SPACE with M then 1.
Display contents of memory, but do not use in calculation: press M, then 1.
These commands are now discussed in more detail.
8.5.1 Clear Memory.
This operation clears the particular memory immediately, and can be used at any time when you are
entering a calculation or when a result is displayed. For example, to clear memory 5, press
SPACE with K, KeySoft prompts "Clear which memory?". Type 5. You are returned to your
calculation.
8.5.2 Store Memory.
This completes the current calculation and stores the result in a memory. For example, to calculate
the result of 3 + 5 and store it in Memory 4, type: 3 + 5 SPACE with S 4.
When you press SPACE with S, the letter S is displayed on the Braille display and "Store memory"
is spoken.
The resulting value of 8 is stored in memory number 4.
8.5.3 Add to Memory.
This completes the current calculation and adds the result to the existing contents of a memory. For
instance, after the previous example, Memory 4 contains 8. Now to calculate 9 divided by 5, and to
add the result to Memory 4, press : 9 / 5 SPACE with A 4.
When you press SPACE with A, the letter A is displayed on the Braille display and "Accumulate
memory" is spoken.
The calculation is evaluated, resulting in 1.8. This is then added to Memory 4, to give a value in
Memory 4 of 9.8. (Assuming Memory 4 already contains 8).
