Description: Example program from SAS/ETS User's Guide,
             The SASEQUAN Interface Engine

      Notes: Read this before you run this sample.
             The sample data provided resides in the ets/sasmisc folder.
             If you are using automap=READONLY, then you must copy the
             map of your incoming XML data to a writeable folder before
             using it. So, define a system environment variable
             ,QUANDL, to the path of your  writeable folder containing
             the quanex06.map file and QUANEX06.xml.
             To assign a fileref to the external file to be processed,
             use the following form of the libname statement:

           libname quan sasequan "%sysget(QUANDL)"
              FORMAT=XML
              OUTXML=quanex06
              AUTOMAP=replace
              MAPREF=MyMap
              XMLMAP="%sysget(QUANDL)quanex06.map"
              APIKEY='<your Quandl apikey>'
              IDLIST='<your list of Quandl codes>'
              START='<trim_start>'
              END='<trim-end>'
