The initial value of *binary-file-type* depends on the host CPU and the LispWorks implementation. See Naming conventions for FASL files.
The variable *binary-file-type* is the file type that load and require recognize as a binary (FASL) file (in addition to any additional file types in *binary-file-types*).
Normally you should not set *binary-file-type*. If you need to load files with another type, push that type on to *binary-file-types*.
