This manual sometimes refers to example files in the LispWorks library via a Lisp form like this:
(example-edit-file "editor/commands/space-show-arglist")
These examples are Lisp source files in your LispWorks installation under lib/7-1-0-0/examples/. You can simply evaluate the given form to view the example source file.
Example files contain instructions about how to use them at the start of the file.
The examples files are in a read-only directory and therefore you should compile them inside the IDE (by the Editor command Compile Buffer or the toolbar button or by choosing
Buffer > Compile
from the context menu), so it does not try to write a fasl file.
If you want to manipulate an example file or compile it on the disk rather than in the IDE, then you need first to copy the file elsewhere (most easily by using the Editor command Write File or by choosing
File > Save As
from the context menu).
