Compiling the Lisp source code is also easy:
(setf (search-list "code:") '("/usr/lisp/code/"))
(load "code:worldcom.lisp")
Again, the first line defines a search list variable, so that the file worldcom.lisp can find the Lisp sources. As each file is compiled, the name of the file is printed on the terminal. For each file a .fasl will be generated. Also, a single error log will be generated in the file code:compile-lisp.log.
This step takes about an hour and a half.
