Changing Memory Values

If you are not yet familiar with the use of memory registers, go here.

You cannot change memory values directly. This is because ActiCalc requires that every calculation operation be reflected completely on the tape so that the operations can be repeated reliably at a future time.

Even though you cannot change the memory register directly, you can easily change its value by changing the entries on the tape that led to the memory register being stored. This sounds complicated, but it is really very simple. Consider the following example.

In this case, we entered 123+456*18.2, then pressed the

button in the SCI panel and finally the

button for register 2 in the MEM panel. Rows 11-14 calculated the value and row 15 stored it. To change the value stored in the memory register, you can change any of the entries in rows 11-13, or you could insert or delete rows before row15.

Notice that the value of the register changes as you move the cursor up and down. The register displays always reflect the calculations up to the cursor location.
