File-in Format
File-in format is the original Smalltalk format for representing classes as text files. These can be "filed in" to the VisualWorks IDE to generate any classes not already contained in the Smalltalk image. Every file-in document provides a simple textual representation of a Smalltalk class, or classes, in a text file with a .st suffix. It is still supported in VisualWorks, but has been superseded by a Parcels mechanism. There are examples in file-in format in the examples subdirectory.
