Description

   This function returns a count of the number of elements in an attribute list. 
   Certain legacy systems, most often those using the Column Aligned Text (CAT) 
   format, require such a count to be output. Consequently, this function is 
   most commonly used to compute a value for a TRANSFER clause in a relation 
   definition. Refer to the @Relate section in this chapter for details.
