5.2.3 Load a Retina

Retina In order to load a new retina and - at the same time - to get an initial configuration click the button Retina. A new window will appear, which enables the user to choose a retina file from an arbitrary directory. SCARLET'S retina interpreter will accept every valid RDL-program. Other files are rejected returning an error message in a separate window ( i.e., parse error... together with more detailed information on the kind of error).
 

If the file has been accepted the settings will change. The name of the retina - which has been determined in the headline of the belonging program using (RETINA <Name>;), - and its range will be shown in the settings-box behind Retina:
But, of course, it is much more important to notice that the initial configuration of the retina loaded is displayed in the pane of the window.


 

Reload Sometimes it may be desirable to restore the initial configuration again after having performed some steps of the simulation. But now that the name of the file is already known it is not necessary to open the load window and to do all the choosing again. In this case simply use the Reload button.
