 If you attempt to WRITE or QUERY a connection, that has not yet been opened, CONNECT will
 look for the HOSTPORT specification in a user variable called "connect_CNXNNAME" (where CNXNNAME is the name of the connection). If found, CONNECT will attempt an auto-connection to that network location before attempting the WRITE/QUERY.  This is equivalent to inserting the command:\\
+<code>
    -connect name $connect_name
-To use this feature the default HOSTPORT should be predefined, as in the [[jvs:fscan:manual:chapter1:configfile|CONFIG]] file.
+</code>
+For example, if you routinely connect to a DBAX database server, you could define 'connect_dbax' in your  [[jvs:fscan:manual:chapter1:configfile|CONFIG]] file as:
+    <uservarb name="connect_dbax">sagan.dhe.duke.edu:5570</uservarb>
+Then you could communicate with that server by simply using commands like:
+<code>
+   -connect dbax query "select subjid,exam,sex,age from exams" 2 examtable
+</code>
