Custom conversion example

As an example, you might implement custom-conversion functions to do the following, expressed in pseudocode: 
IF input field 1 satisfies condition A
THEN 
DO calculation X on input field 7
OUTPUT data to output column 7
ELSE
DO calculation Y on input field 6
OUTPUT data to output column 5

The custom-conversion function feature is available only on computers with operating systems that support dynamic linking.
