RE: Compiler error on packed field redefine

["Buzz Fenner" <bfenner@xxxxxxxxxxxxxxxx>]

Ah...Thanks Bob (and Lois).  My thinking was backwards and was looking at
the redefine in terms of offset.  I was thinking of specifying the packed
length, not unpacked.  Thanks guys.

The From-To columns indicate the start and end locations in the database
record where the field is located. No the length of the fields. A quick
calculation of your packed field to me, indicates that:

 16 to 19 P 0
 16 through 19 = 4
 4 * 2 = 8
 8 - 1 = 7

Hence you field is 7 packed, so on a length-notation D spec you need to
code it as   7P 0
Unless the field is the rare "even packed" field, in which case it would
be 6P 0 look at the DDS source for the file and make the D spec look the
same.
