<div><p>The keyword REFACCPTH in data description specifications (DDS)
|
|
allows you to use another file's access path specifications. When the file
|
|
is created, the system determines which access path to share. </p>
|
|
<p>The file using the REFACCPTH keyword does not necessarily share the access
|
|
path of the file specified in the REFACCPTH keyword. The REFACCPTH keyword
|
|
is used to only reduce the number of DDS statements that must be specified.
|
|
That is, rather than code the key field specifications for the file, you can
|
|
specify the REFACCPTH keyword. When the file is created, the system copies
|
|
the key field and select/omit specifications from the file specified on the
|
|
REFACCPTH keyword to the file being created.</p>
