To initialize the number of memories (to return the number
to 26), enter a zero for the value in the memory expansion
sequence outlined above.
* Though a maximum of 50 memories can be added, if a
program has already been stored and the number of
remaining steps is less than the desired expansion, an
error will be generated. The size of the memory
expansion must be equal to or less than the number of
steps remaining.
* The expansion procedure ( expansion value) can
also be stored as a program.
• Using expanded memories
Expanded memories are used in the same manner as
standard memories, and are referred to as Z[1], Z[2], etc.
The letter Z followed by a value in brackets indicating the
sequential position of the memory is used as the memory
name. (Brackets are formed by for "[" and
for "]".) After the number of memories has been expanded
by 5, memories Z[1] through Z[5] are available. The use of
these memories is similar to that of a standard computer
array, with a subscript being appended to the name.
