+   Inserts a new record into the database. The record is not neccesarily
+   inserted at the end of the database, but may be inserted at any
+   position depending on where the first free slot is found.

+  <para>
+   The record data is passed as an array of field values. The elements in
+   the array must correspond to the fields in the database. If the array
+   has less elements than fields in the database, the remaining fields
+   will be set to null.
+  </para>
+  <para>
+   Most field values can be passed as its equivalent php type e.g. a long
+   value is used for fields of type PX_FIELD_LONG, PX_FIELD_SHORT and
+   PX_FIELD_AUTOINC, a double values is used for fields of type
+   PX_FIELD_CURRENCY and PX_FIELD_NUMBER.
+   Field values for blob and alpha fields are passed as strings.
+  </para>
+  <para>
+   Fields of type PX_FIELD_TIME and PX_FIELD_DATE both require a long
+   value. In the first case this is the number of milli seconds since
+   midnight. In the second case this is the number of days since 1.1.0000.
+   Below there are two examples to convert the current date or timestamp
+   into a value suitable for one of paradox's date/time fields.

+    The julian day count as passed to <function>jdtogregorian</function>
+    has a different base of 1.1.4714 b.c. and must therefore be calculated
