Replay function
• This function stores the latest operation executed. After execution
is completed, pressing [ 2nd ] [Ÿ] or [ 2nd ] [ź] key will display the
operation from the beginning or the end. You can continue moving
the cursor by [Ź] or [Ż] to edit it. To delete a digit, press [ DEL ].
( or, in overwrite mode, just type over the digit). See Example 1.
• The replay function can keep input digits up to 256 characters for
SR-270ll / SR-275. After execution is completed or during entering,
you can press either [2nd ] [Ÿ] or [ 2nd ] [ź] to display previous
input steps and edit values or commands for subsequent execu-
tion. See Example 2.
(Note) : The replay function isn’t cleared even when [ ON / AC ] is
pressed or power is turned off, so contents can be
recalled even after [
ON / AC ] is pressed.

Memory variable
• The calculator has nine memory variables for repeated use : A, B,
C, D, E, F, M, X, Y. You can store a real number in any of the nine
memory variables. See Example 5.
* [ STO ] + . A . ~ . F . , . M . , or . X . ~ . Y . lets you store values to
variables.
* [ 2nd ] [ RCL ] or [ ALPHA ] + . A . ~ . F . , . M . , or . X . ~ . Y . re-
calls the value of variable.
* [ 0 ] [ STO ] + . A . ~ . F . , . M . , or . X . ~ . Y . clears the content to
a specified memory variable.
* [ 2nd ] [ Mcl ] [ = ] clears all variables.
