<h1 class="topictitle1">Commands and command help</h1>
|
|
<div><p>Command prompting and online command help are powerful features
|
|
of CL commands.</p>
|
|
<p> If you have developed one or more of your own CL commands, you know that
|
|
all of the command prompting capabilities used by IBM<sup>®</sup> CL commands are available for you to
|
|
use for your commands. The same is true for command help; the same capabilities
|
|
for help provided for IBM-provided commands are also available for you to
|
|
use to create online help.</p>
|
|
<p>The first step is to understand how the connections work between commands
|
|
and command help. </p>
|
|
<ul><li>Command help information is stored in panel group objects. The symbolic
|
|
object type for a panel group is *PNLGRP. A help panel group consists of
|
|
help modules. Each help module has a help module name.</li>
|
|
<li>There are two parameters on the <span class="cmdname">Create Command (CRTCMD)</span> command
|
|
that make the connection between a command (*CMD) object and an online help
|
|
panel group: <strong>HLPID</strong> (Help identifier) and <strong>HLPPNLGRP</strong> (Help panel
|
|
group).</li>
|
|
<li>There are four types of command help modules in an online help panel group:
|
|
<ol><li>Command-level help module</li>
|
|
<li>Parameter-level help module</li>
|
|
<li>Command examples help module</li>
|
|
<li>Command error messages help module</li>
|
|
</ol>
|
|
</li>
|
|
</ul>
|
|
<p>When you try to view the help for a CL command (for instance, by pressing
|
|
the F1 (Help) key while prompting the command), i5/OS™ determines whether the command has
|
|
a help panel group associated with the command. If the command was created
|
|
specifying a panel group name for the HLPPNLGRP parameter, or was changed
|
|
by the <span class="cmdname">Change Command (CHGCMD)</span> command to have a help panel
|
|
group associated with the command, the help stored in the panel group is
|
|
retrieved, formatted, and displayed. i5/OS attempts to retrieve help from the
|
|
following help modules in the help panel group: </p>
|
|
<ul><li>A command-level help module that has the same name as the value specified
|
|
for the HLPID parameter when the command was created or changed. For example,
|
|
if command STRPAY was created specifying HLPID(STRPAY), i5/OS looks for
|
|
a help module named STRPAY.</li>
|
|
<li>A parameter-level help module for each command parameter, with the exception
|
|
of constant parameters. The help module name must be the command's HLPID value
|
|
followed by a forward slash character followed by the parameter keyword name.
|
|
For example, if command STRPAY has a HLPID value of STRPAY and a parameter
|
|
named TITLE, i5/OS looks
|
|
for a parameter-level help module named STRPAY/TITLE.</li>
|
|
<li>A help module containing one or more examples of using the command.
|
|
The help module name must be the command's HLPID value followed by a forward
|
|
slash character followed by COMMAND/EXAMPLES. For example, if command STRPAY
|
|
has a HLPID value of STRPAY, i5/OS looks for a command examples help module named
|
|
STRPAY/COMMAND/EXAMPLES.</li>
|
|
<li>A help module containing the list of monitorable messages that may be
|
|
signaled from the command. The help module name must be the command's HLPID
|
|
value followed by a forward slash character followed by ERROR/MESSAGES. For
|
|
example, if command STRPAY has a HLPID value of STRPAY, i5/OS looks for
|
|
a command examples help module named STRPAY/ERROR/MESSAGES.</li>
|
|
</ul>
|
|
<p>When viewing extended CL command help on a 5250 terminal (or using 5250
|
|
emulator software), command-level and parameter-level help sections are required,
|
|
and the examples and error messages help sections are optional. If the command-level
|
|
help section or any parameter-level help section is not found in the online
|
|
help panel group, diagnostic message CPF6E01 (Help information is incomplete)
|
|
is displayed at the bottom of the help display. If the examples or error
|
|
messages help modules are not found, no diagnostic message is displayed.</p>
