LispWorks uses the following naming conventions for fasl files, and it is recommended that you should use them too, to ensure correct operation of load and so on.

Table 10.2 Naming conventions for FASL files
Machine Architecture	Fasl File Extension
Alpha	`.afasl`
RS/6000	`.rfasl`
HPPA	`.pfasl`
DECstation	`.dfasl`
SPARC	`.wfasl`
Clipper	`.cfasl`
386	`.3fasl`
Other PC	`.fsl`

You can find the fasl file extension appropriate for your machine by looking at the variablesystem:*binary-file-type*. The variablesystem::*binary-file-types* contains a list of all the file extensions currently recognized byload.

Example

SYSTEM 5 > (with-output-to-fasl-file (s "/tmp/foo.fasl")
     (dump-form '(print 'hello) s)) 
0 
NIL
SYSTEM 6 > (load "/tmp/foo.fasl") 
; Loading fasl file /tmp/foo.fasl
HELLO 
#P"/tmp/foo.wfasl"
