A function_call can consist of a call to either SQL Functions or a 4D function (4d_function_call). Both types of functions manipulate data and return results and can operate on one or more arguments.
This example uses the SQL COUNT function:
C_LONGINT(vPersonNumber)
Begin SQL
SELECT COUNT (*)
FROM SALES_PERSONS
INTO :vPersonNumber;
End SQL
