Specifying a Function's Storage Type

When creating a function, you must specify the method used to store values returned by the function.

• Simple - A simple function only stores the most recent value calculated. Simple functions do not store historical values and therefore do not require much memory to perform their calculations.
• Series - Series functions can store previous as well as current values. Because series functions store more information, they also require more memory to perform their calculation.
• Auto-detect - If you do not know the function's storage type, select Auto-detect and the function storage type is automatically determined by EasyLanguage algorithms. However, if you choose this option, the maximum amount of memory needed to perform calculations based on series data is assumed.
