The table schema require each line to have 100 distinct, if empty, columns
and the data fills a variable number of columns. Did not think of that as
the problem but it would be for any relational database.


  The column separator, a comma, is present for each column, but those
without content are not automagically assigned NULL when inserting so the
data appears to not have the proper number of columns. So, a simple UPDATE
command will change the NA to NULL in each table.
