* Use the fields in the *Options* tab to specify additional information:
* Move the *OID* switch to the *Yes* position to include the *OID* column.
The *OID* is a system-assigned value that may not be modified. The default
is *No*.
* Move the *Header* switch to the *Yes* position to include the table header
with the data rows. If you include the table header, the first row of the
file will contain the column names.
* If you are exporting data, specify the delimiter that will separate the
columns within the target file in the *Delimiter* field. The separating
character can be a colon, semicolon, a vertical bar, or a tab.
* Specify a quoting character used in the *Quote* field. Quoting can be
applied to string columns only (i.e. numeric columns will not be quoted)
or all columns regardless of data type. The character used for quoting can
be a single quote or a double quote.
* Specify a character that should appear before a data character that matches
the *QUOTE* value in the *Escape* field.
* Use the *NULL Strings* field to specify a string that will represent a null
value within the source or target file.
