Hi Bart,

The simplest way is using ALTER TABLE, but this doesn't copy your data, 
it simply changes the column definition:

ALTER TABLE lib/file ALTER COLUMN eancode SET DATA TYPE CHAR(13) 

If you don't want to do this in place then CRTDUPOBJ the file first, and 
alter the copy. Another way to do this is to CREATE TABLE the file with 
the new layout, then do an INSERT with subselect like this:

INSERT INTO newfile SELECT * FROM oldfile

Hope this helps.
