RE: Defining fields in logical file

Titus,

Sorry, there's no way do to what you want with DDS.  If the logical has a
different format than the physical, like yours will with the additional
field, then you have to specify every field.  If the physical changes, and
you want the new field to show in the logical, then you'd have to add it.
If you don't need the new field in the logical then you'd just need to
recompile the logical.

As someone else mentioned, SQL provides a way to do this.  But you already
mentioned that you don't want to use it.  (create view myview
substr(myfield,1,2), A.* from myfile A)  Note that views can't be keyed.

HTH,
Charles
