|

|
|
<div><p>Before deciding whether to save or release a held optical file,
|
||
|
|
you might want to view information that can influence save and release decisions. </p>
|
||
|
|
<p>The Work with Held Optical Files display provides this means, in addition
|
||
|
|
to the ability to save and release held optical files. The save and release
|
||
|
|
functions are also available as optical-specific functions of the HFS Control
|
||
|
|
File System API. </p>
|
||
|
|
<p>The Work with Held Optical Files display provides a convenient way to list
|
||
|
|
and manage any held optical files on the system. Use the Work with Held Optical
|
||
|
|
Files (WRKHLDOPTF) command to access the Work with Held Optical Files display. </p>
|
||
|
|
<p>Options on the Work with Held Optical Files display are selected to display
|
||
|
|
the use (open instances) of files, as well as to save and release held files.
|
||
|
|
By default, using option 9 (Save) on the Work with Held Optical Files display
|
||
|
|
causes the automatic release of a held file after it is saved. </p>
|
||
|
|
<p>The functions provided by option 9 (Save) and option 6 (Release) are also
|
||
|
|
available as the optical-specific functions, Save Held Optical File and Release
|
||
|
|
Held Optical File, of the Control File System API in the <a href="../apis/qhfctlfs.htm">Programming</a> topic.</p>
|
||
|
|
<p>Unlike option 9 (Save), the Save Held Optical File function of the Control
|
||
|
|
File System API does not automatically release a held file after it is saved.
|
||
|
|
Therefore, an explicit release request is needed afterward.</p>
