<div><p>To determine the best approach for a particular job, you must first
determine which program should control the routing step. </p>
<div class="section"><h4 class="sectiontitle">Using QSYS/CMD for interactive jobs - benefits</h4><div class="p">The
IBM-supplied command processor QSYS/QCMD gives the greatest flexibility in
terms of making functions available to workstation users. Using QCMD to control
the routing step gives you the following benefits: <ul><li>The attention program is activated if it is specified in the user profile.</li>
<li>The initial program that is specified in the user profile is called.</li>
<li>The initial menu that is specified in the user profile is called.</li>
<li>The user is placed in System/36™ environment as it is specified
in the user profile.</li>
</ul>
In addition, the default using QCMD brings you to the Main Menu where
you can enter commands directly, including the CALL command, which is used
to call user-written functions. Menu options with online help are provided
to give easy access to system functions. Also provided are command selection
menus, quick access to index search, and the command entry function (called
by CALL QCMD). The command entry functions are intended primarily for programmers
and operators who require the full range of functions available through the
direct use of commands.</div>
</div>
<div class="section"><h4 class="sectiontitle">Calling a user program directly for interactive jobs - benefits</h4><p>Your
programs can be directly called to control the routing steps for interactive
jobs. These programs can be designed to give a more specialized access to
functions needed by your workstation users than the IBM-supplied programs
give. In addition, because your programs are tailored for specific functions,
they should typically require even less system resource to support their running
than the IBM-supplied programs. You may also want to provide functions such
as an initial program and initial menu.</p>
