The <var class="product">Imagine Transparency</var> facility allows <var class="product">Model 204</var> programs to access files stored in the <var class="product">Imagine</var> database as if they were local files. This facility is available in <var class="product">Model 204</var> Version 8.0 and later.

While a fair amount of setup is required to define and populate the <var class="product">Imagine</var> files being accessed in Transparency mode, and create <var>Imagine</var> broker processes to provide <var class="product">Model 204</var> access to the <var class="product">Imagine</var> files, very little setup is required on <var class="product">Model 204</var>.

First, an [[JANUS_DEFINE#IMAGINET|IMAGINET]] port must be defined in an Online that would be using <var>Transparency Mode</var>. The number of connections required is the maximum number of threads simultaneously accessing <var class="product">Imagine</var> files in the Online. The total number of threads in the Online is, of course, an upper bound for this number.

Then, each <var class="product">Model 204</var> file hosted on <var class="product">Imagine</var> needs to [[DEFINE DATASET command#IMAGINE|be allocated]] as an <var class="product">Imagine</var> file. For example:
<p class="pre">ALLOCATE SOMEFILE WITH IMAGINE
</p>
Once this is done, any reference to <var>SOMEFILE</var> in a<var class="product">Model 204</var> application (including in file groups) would access the data from <var class="product">Imagine</var> via the <var>IMAGINET</var> port. Note that a single <var class="product">Model 204</var> file can corresponding to many <var class="product">Imagine</var> files if record types are used.
