You can delete all of the saved items stored in the "Recall Items". Select "Delete
All Saved Items" from the "Memory Functions" menu, or press "Enter-D" from
the calculation line.
"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.
You can also define variables directly from the calculation line by typing
"variable=expression" and press "Enter" to save the variable.
If you select the Statistics function, a dialog opens, which consists of a list box
containing all the stored variables and their values, a list box displaying the
results of several functions, and a "Close" button. Press "Backspace-T" to
activate this function from the calculation line,
Press "Space" to select each variable in the list that you want included in the
data set for which the statistics are calculated. TAB to the "result" list to view the
sum, average, variance, and standard deviation of the selected variables. You
can also select items from the result list and copy them to the clipboard.
