Storage Register Operations
When numbers are stored or recalled, they are copied between the
display (X-register) and a data storage register. The total number
of available storage registers will depend on the current word size
and the amount of available memory, as explained above.
Of those registers available, up to 32 can be addressed directly by
name (0to9and AtoF,.0to.9 and .A to .F); the remainder (up to 69
in word size 16) can only be accessed indirectly, using the Index
register (described later in this section). Since the highest-
numbered registers are the first to be converted to program
memory, it is wisest to store data in the lowest-numbered registers
available. (See also the diagram on the inside back cover.)
Storing and Recalling Numbers Directly
To store or recall numbers between one of the directly accessible
data storage registers and the X-register, press {OtoF,.0to.F,
(1]} or {0 to F, .0 to .F, [1]}. The operation replaces the
contents of the addressed register with a copy of the X-register
contents; the operation lifts the stack (if it is enabled) and
then places a copy of the addressed register contents into the
X-register.
If you attempt to address a nonexistent register (including one that
cannot exist because the memory space is occupied by program
lines), the display will show Error 3. Remember also that you can
lose stored data values when data storage registers are
automatically converted to program memory, and that the highest-
numbered registers are converted first.
