12.15.3 Loading old data files

Binary files created with hcl:dump-forms-to-file or hcl:with-output-to-fasl-file in LispWorks 5.0, LispWorks 4.4 or LispWorks 4.3 can be loaded into LispWorks 5.1 using sys:load-data-file .

Note: because the default fasl extensions have changed on some platforms since LispWorks 4.4 you may need to do something like this to load old binaries:

(let ((sys:*binary-file-type* "fsl"))
  (sys:load-data-file "C:/lww44.fsl"))
