set-filename in drscheme:unit:definitions-text

Set the path name for the file to be saved from or reloaded into this editor. This method is also called when the filename changes through any method (such as load-file).

The filename of an editor can be changed by the system in response to file loading and saving method calls, and such changes do not go through this method; use on-load-file and on-save-file to monitor such filename changes.
