"Save Items" is a dialog that allows you to define variables according to the current
expression or result in the calculator and save them for future use. The dialog
contains an edit box for typing in the variable name, a "Confirm" button and a
"Cancel" button. SELECT "Save Items" from the "Memory Functions" menu, or
press "Backspace-S" from the calculation line.
When the dialog is opened, the "item name" edit box is focused. Type a name for
the variable, and press "Enter" or move to "confirm", and press "Enter". The
current expression or result is then saved under the variable name you just
specified.
If you type names under variables which have already been created, you are
prompted, "Replace variable xx with current value? Yes". If you type function
names like "sin", "cos", or "pi" as a variable name, you are warned, "Invalid item
name", as you cannot use these functions in variable names.
