<h1 class="topictitle1">HLPCMDKEY (Help Command Key) keyword for display files</h1>
|
|
<div><p>Use this record-level keyword to return control to your application
|
|
program after a command attention (CA) or command function (CF) key is pressed
|
|
on an application help record format.</p>
|
|
<div class="section"><p>This keyword is specified on the application help record format.
|
|
For control to return, the command key must be specified on both the application
|
|
record format and the application help record format.</p>
|
|
<p>This keyword has
|
|
no parameters.</p>
|
|
<p>A CA or CF key must be specified either at the file level
|
|
or on the help record containing the HLPCMDKEY keyword. If no CAnn or CFnn
|
|
keys are specified at the file level or on the help record, a warning message
|
|
(severity 10) is issued. If all the CAnn and CFnn keys specified at the file
|
|
level and on the same help record as the HLPCMDKEY keyword have option indicators,
|
|
a warning message (severity 10) is issued. When a response indicator is specified
|
|
on a CA or CF key on the application help record format, a warning message
|
|
(severity 10) is issued and the response indicator will be ignored.</p>
|
|
<div class="p">If
|
|
you specify this keyword on the help record and the display station user presses
|
|
one of the command keys that is specified on both the application record and
|
|
the application help record, the following case happens: <ul><li>If the command key is a CAnn key, no input data from the application record
|
|
format is transmitted to the application program.</li>
|
|
<li>If the command key is a CFnn key, input data from the application record
|
|
format is transmitted to the application program.</li>
|
|
<li>The command key will be returned to the application program.</li>
|
|
</ul>
|
|
</div>
|
|
<p>The command key must be specified on both the application record
|
|
format and the application help record format. If the command key is specified
|
|
only on the application record format, the command key will not be allowed
|
|
when the application help record format is displayed. If the command key is
|
|
specified only on the application help record format, the command key will
|
|
function as the Enter key and control will not return to the application program.</p>
|
|
<p>You
|
|
cannot specify HLPCMDKEY on subfile (SFL keyword), subfile control (SFLCTL
|
|
keyword), or user-defined (USRDFN keyword) record formats.</p>
|
|
<p>You cannot
|
|
specify the HLPCMDKEY keyword in a file containing the USRDSPMGT keyword.</p>
|
|
<p>Option
|
|
indicators are not valid for this keyword.</p>
|
|
</div>
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
|
the HLPCMDKEY keyword. The first record is the application record format and
|
|
the second record is the application help record format.</p>

<p>If the user is at the

|
application help display, the following case occurs:</p>
|
|
<ul><li>If the CMD1 key is pressed, control is returned to the application program,
|
|
but no data from the application record format is transmitted to the application
|
|
program. Response indicator 11 is not set on since it was specified on the
|
|
help record format rather than the application record format.</li>
|
|
<li>If the CMD12 key is pressed, control is returned to the application program
|
|
and data from the application record format is transmitted to the application
|
|
program. Response indicator 12 is on.</li>
|
|
<li>If the CMD5 key is pressed, it functions as the Enter key. The same CA
|
|
or CF keys must be specified on both the application record format and the
|
|
application help record format for control to be returned to the application
|

program.</li>
|
|
<li>If the CMD3 key is pressed, it functions as the Enter key. The corresponding

|
CA or CF keys must be specified on both the application help record format
|
|
and the application record format for control to be returned to the program.</li>
|
|
<li>If the CMD4 key is pressed, it results in a message indicating that the
|
|
CMD4 key is not allowed. The same CA or CF keys must be specified on both
|

the application record format and the application help record format in order
|
|
for control to be returned to the application program.</li>
