==Description==
<p>
This parameter indicates the number of segments worth of space to be allocated in the record locking table for recordsets for [[Imagine Transparency]] files. These files can have an essentially unlimited number of segments on <var class="product">Imagine</var> but that's irrelevant for the purposes of the <var>IMGSEGS</var> setting, as recordsets are thread-specific and the number of segments in a file is just a limit on the number of records that can be accessed in a <var class="product">Model 204</var> file that's backed by SYSOPT2 parameterImagine</var> files in a session.
</p>
<p>
Since the number of records in a segment is 49,152, the default <var>IMGSEGS</var> of 32 allows for 1,572,864 records in a sessions which is almost certainly more than enough for most purposes. If the [[SYSOPT2 parameter]] X'40' bit is set, the required record locking table space per recordset in an <var class="product">Imagine</var> file is roughly four times <var>IMGSEGS</var>.
