To compile the file associated with the current buffer, choose
File > Compile . To compile multiple files associated with
buffers, select them in the buffers view and choose File >
Compile . If there is not a current buffer, the menu command
File > Compile... is available, which prompts for a file to
compile. Note: this command calls the Common Lisp function ; it
creates the fasl file but does not load it. You can use File >
Load to later load the fasl. To compile a file (or files) and
load the resulting fasl file(s) with a single command, choose
File > Compile and Load . If there is not a current buffer, the
menu command File > Compile and Load... is available. LispWorks
