*source-pathname*

When a function, defstruct accessor, flavor method, or macro is defined, and when symbol-function is setf'ed, the value of this variable is recorded as the place of definition. During a load of a source file or during a compile-file this variable is bound to the name of the file being loaded or compiled. Programs, such as editors running Lisp as a subprocess, or users typing to the top-level may themselves bind this variable to any pathname designator (a string or a pathname object) they wish, and the information will be recorded except when load is used to transmit the definition to Lisp.

This variable is not bound when a fasl (compiled Lisp) file is loaded.

See also source-file-recording.htm for general information on source file recording in Allegro CL.
