Causes a value to be treated as a specific type of data
expression - any formula or value
type - what type to assign to the result: 0 = none, 1 = price, 2 = volume
This function is rarely needed because RealTest automatically determines the type of most calculated values correctly.
The data type of a value is only important when the value is used in multi-bar formulas or indicators that cross a split date.
Only use this function if you have observed incorrect split handling in, for example, a complex Data Section formula.
