## *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.
