Defining Two New Function Fields

To add the function fields you require, press F10 to display the Define Objects panel. You can define both function fields at this point.

Here are the details for the two function fields:

Finished race—a function field that appears on each subfile record and evaluates whether or not the horse finished a race. Its value is derived from the value of the Entry Status field. This requires a usage of DRV. You can edit the default field details directly by typing Y in Edit field.
No. of finishers—a function field in the subfile control and is a sum of the values in the Finished race field of each subfile record. It is defined as a REF field based on the field Finished race.

Type the new function fields.

Press Enter.
