View source for Filed modules and libraries

Modules and libraries can be components of a model. If you are building several similar models,
or if you are building a large model composed of similar components, you can create modules
and libraries for reuse. (See [[Building Functions and Libraries]] for details about
libraries.) To use a module or library in more than one model, create a '''''filed module''''' or '''''filed library'''''.

'''Creating a filed module or library''':
To create a filed module or library:
# Create a module by dragging the module icon from the node palette onto the diagram, and give it a title.
# Create functions and variables in the module, or create them elsewhere and move them into the module.
# '''[[To_change_the_class_of_an_object|Change the class]]''' of the module to '''Module''' [[File:Chapter19_14.png]] or '''Library''' [[File:Chapter19_15.png]]
# The '''Save As''' dialog appears. Give the filed module or library a name and save it.
#  If you want the original model to load the new filed module or library the next time it is opened, save the model using the '''Save''' command.

'''Locking a filed module or library''': To prevent a filed module or library from being modified, lock it:
#  Close the filed module or library, or close Analytica.
#  In Windows Explorer, select the filed module or library.
#  Select '''Properties''' from the '''File''' menu. [[File:Chapter19_16.png]]
# Check the ''Read-only'' checkbox.
# Close the '''Properties''' window

'''Adding a module to a model''': To add a filed module to the active model, use the '''[[Add Module dialog]]'''. You can either embed a copy of the module or link to the original of the filed module.

'''Adding library to a model''': To add a filed library to the active model, use the '''[[Add Module dialog]]'''. You can either embed a copy of the library or link to the original of the filed library.
When you select '''Add Library''' from the '''File''' menu, the '''Open File''' dialog always opens up to fixed directory, regardless of the current directory settings or previous changes of directories. The
directory is determined by a registry setting in <code>/Lumina Decision Systems/Analytica/
3.0/AddLibraryDir</code>, which is set by the Analytica installer to <code>INSTALLDIR/Libraries</code>.
 
'''Removing a module or library from a model''': To remove a filed module or library from a model, first select it. Then, select '''Cut''' or '''Clear''' from the '''Edit''' menu. An embedded copy is deleted; a linked original still exists as a separate file.

'''Saving changes''':  After you have linked to a filed module or library, the '''Save''' command saves every filed module and library that has changed, as well as the model containing them, in their corresponding files. The '''Save As''' and '''Save A Copy''' In commands save only the active (topmost window’s) model, filed module or filed library
