Returns the value of a data variable at a time using the specified interpolation mode or, or :NA: if the time is before the first or after the last data point. :NA: is also returned it variable passed as an argument is not a Data variable. If mode= 0 the value is computed by interpolating. If mode = 1 the value returned is the later time value (same as :LOOK FORWARD:). If mode is -1 the value returned is the earlier time value (same as :HOLD BACKWARD:).
Note that GET DATA BETWEEN TIMES is slow compared to other functions on data. For example GET DATA BETWEEN TIMES(datavar,Time+1,0) is the same as defining an additional data variable
tshift datavar := TIME SHIFT(datavar,1)
and then using that tshift datavar. Defining the extra variable will give better performance.
Units: GET DATA BETWEEN TIMES(units,time,dmnl) --> units
Example
sales at time 20 = GET DATA BETWEEN TIMES(sales data,20,0)
