We are now using mailmerge very successfully for document assembly
with a number of different documents.

However, if we have only ONE field in the data file that is to be
merged, then word is bringing up a dialog with the following text:

Data fields must be separated from each other by a character called a
field delimiter. Similarly, data records must be separated by a record
delimiter. Use the lists below to select the appropriate delimiter

The source data file basically contains:

FieldName<nl>
FieldValue<nl>
<EOF>

The user has to press OK to continue with the merge

If we have two fields, like in the example below then the dialog does
not appear.

FieldName1,FieldName2<nl>
FieldValue1,FieldValue2<nl>
<EOF>

We want the merge to happen without user involvement, so we want this
dialog to not appear.

I can add a dummy field to the output data field, but is there a
better way?
