<p><strong>Bytes available.</strong> The total length of all data
available.</p>
<p><strong>Bytes returned.</strong> The length of the data actually returned.
The number of bytes returned is always less than or equal to both the number of
bytes available and the receiving variable length.</p>
<p><strong>Currently active jobs.</strong> The number of jobs currently active
in the subsystem. This number <em>includes</em> held jobs but <em>excludes</em>
jobs that are disconnected or suspended because of a transfer secondary job or
a transfer group job. If the subsystem status is *INACTIVE, this number is
0.</p>
<p><strong>Maximum active jobs.</strong> The maximum number of jobs that can
run or use resources in the subsystem at one time. If the subsystem description
specifies *NOMAX, indicating that there is no maximum, this number is -1.</p>
<p><strong>Number of subsystem entries returned.</strong> The number of
subsystems for which entries are returned. This number determines how many
times the entire set of fields describing a subsystem is repeated.</p>
<p><strong>Number of storage pools defined.</strong> The number of storage
pools defined for the subsystem. The maximum number of storage pools for a
subsystem is currently 10. This number determines how many times the pool ID,
pool name, pool size, pool activity level, and reserved fields are repeated.
Those five fields are repeated as a group for each pool defined for the
subsystem.</p>
<p><strong>Offset to first subsystem entry.</strong> The number of bytes from
the first byte of the receiver variable to the information for the first
subsystem.</p>
<p><strong>Pool activity level.</strong> The maximum number of jobs that can be
active in the pool at one time. If the pool name indicates a system-defined
pool, the number returned is 0.</p>
<p><strong>Pool ID.</strong> The pool ID for the subsystem pool.</p>
<p><strong>Pool name.</strong> The name of the subsystem pool. If the pool is
user-defined, the value of this field is *USERPOOL. If the pool is
system-defined, the value is one of these names:</p>
<table cellpadding="5">
<!-- cols="15 85" -->

<td align="left" valign="top"><em>*BASE</em></td>
<td align="left" valign="top">The system base pool, which can be shared with

<p>The Change Shared Storage Pool (CHGSHRPOOL) command specifies the size and
activity level of shared pools.</p>
<p><strong>Pool size.</strong> If the pool name is *USERPOOL, the amount of
storage, in kilobytes, that the pool attempts to allocate. If the pool has any
other name, the value of this field is 0.</p>
<p><strong>Reserved.</strong> An ignored field.</p>
<p><strong>Secondary language library name.</strong> The name of the
subsystem's secondary language library.</p>
<p><strong>Sign-on device file library name.</strong> The name of the library
in which the sign-on device file resides.</p>
<p><strong>Size of a subsystem entry.</strong> The number of bytes in the entry
for a subsystem.</p>
<p><strong>Subsystem description library name.</strong> The name of the library
in which the subsystem description resides.</p>
<p><strong>Subsystem description name.</strong> The name of the subsystem about
which information is being returned.</p>
<p><strong>Subsystem description text.</strong> The text description of the
subsystem description. The field is blank if there is no text description.</p>
<p><strong>Subsystem extended status.</strong> Possible values that can be
returned for subsystem extended status are:</p>
