Example 48.2 Retrieving Data by Using the Vintage Date

This example shows how to use the vintage date to retrieve data for exports of goods and services as they existed on that specific date in history. OUTPUT=3 retrieves the new and revised observations only, by the vintage date (VINTAGE=2012-06-14). If OUTPUT=3, then you must specify UNITS=‘lin’. In this example, the UNITS= option is not specified, so it assumes its default value, which is ‘lin’. Specifying a different argument for the UNITS= option (such as ‘chg’) is invalid for OUTPUT= 3, so ’chg’ is replaced by the default value (‘lin’).
