memories can be added in this way, giving you a maximum of 59 memories
(26 + 33).
Note: To restore the default memory configuration—26 memories—specify
Defm 0.
Expanded memories are named A [ 1 ] , A [ 2 ] etc and can be used in the
same way as standard memory variables. See Example 7.
Note: When using array variables, be careful to avoid overlap of memories.
The relation between memories is as follows:
