*open-rename-prefix*

This variable and the variables *open-rename-suffix* and *open-rename-function* work together in renaming a file opened with open with the direction keyword argument either :output or :io and the if-exists keyword argument either :rename or :rename-and-delete. The function that is the initial value of *open-rename-function* renames the existing file by prepending the value of this variable, moving the current file type into the filename, and making the value of *open-rename-suffix* the new type.

The initial value of this variable is the empty string "" and that of *open-rename-suffix* is the string "bak". If all three variables have their initial values, the file foo.txt will be renamed foo.txt.bak (with filename foo.txt and file type bak).

See Extensions to cl:make-package, cl:disassemble, cl:open in implementation.htm for information on the implementation of open.
