My working copy of the dfanoutRecord has already been modified to make VAL a
double instead of a long. Peregrine's suggestion sounds like a good idea. I will
add the support. All future releases of base will have these changes, i.e.

1) VAL and all related fields (HOPR, LOPR, etc) will be DBF_DOUBLE instead of
DBF_LONG
2) dfanout will support the fields SELN, SELN, and SELL just like fanout.
