System Variable Table

The table below shows an alphabetic listing of system variables.

•If a variable has an initial value, the value is shown inside of braces ({ }) in the “Name” column.

•The letter to the left of the slash in the “Op” column indicates whether or not input for the variable is supported, while the letter to the right of the slash indicates whether or not the variable can be deleted (Y: Yes, N: No).

Note: Use the Define command to input a value for a Type “F” (FUNC) variable. For an example about how to do this, see “Define” on page 88.

•The “Type” column indicates the data type of the variable.

Ex: EXPR, St: STR, L: LIST, M: MAT, F: FUNC, _r: Real Number
