Examples This section illustrates some expressions as they might be used in iProcess procedures without functions. (See the next section for functions.) • Test that the field of an iProcess Table record variable has defined contents: TABTAG:TABFIELD <> SW_NA • Test if the user of this procedure is "JOHN": SW_USER:NAME = "JOHN" • Calculate the total price based on number of items, unit cost and VAT rate: (NUM_UNITS * UNIT_PRICE) * VAT_RATE • Test if an order exceeds a customer’s credit limit, defined in an iProcess Table: TOTAL_VALUE >= CUST_REC:CREDIT_LIM • Produce a composite name from components, for example "Mr. John Smith": EMPLOYEE:SALUTATION + " " + EMPLOYEE:FNAME + " " + EMPLOYEE:LNAME • Calculate a date 3 months from now: SW_DATE + @0/0/3/0@ • Test if someone is old enough in an application procedure: (SW_DATE - DATE_OF_BIRTH) > ((AGE_LIMIT * 365) + (AGE_LIMIT / 4))
