Hi James,
You are talking about the include we use to write the user exit for variables in BW.
There are a lot of code examples that Edwin posted in the forum so you can use them to code yours.
A little bit of details on the paramaters in the include:
I-Vnam : The variable name to be calculated
i_t-Var_range: A table that contains all the system's variables data
i_step: The step for variable determination: 0,1,2 or 3.
i_step= 1: used to call default variables, called once per variable before the variable screen is displayed
istep= 2: used for those variables that are not ready for input, called after the variable screen is displayed
i_step=3 : Used for valiadation purposes, and called after isep=2
e_t_range: Is the table that the exit populated the varaible value to.contains the following important fileds:
   low: contains the value of the lower limit for intervals, for text variables it contains the text and for formula vatiables the calculated value.
   high: contains the upper limit for intervals
   sign: ususally I (Include), can be also E (Exclude)
   opt: usually EQ (Equal) or BT(Between)
