declare-ccl-program is a Lisp macro in `ccl.el'.

(declare-ccl-program NAME &optional VECTOR)

Declare NAME as a name of CCL program.

This macro exists for backward compatibility. In the old version of
Emacs, to compile a CCL program which calls another CCL program not
yet defined, it must be declared as a CCL program in advance. But,
now CCL program names are resolved not at compile time but before

Optional arg VECTOR is a compiled CCL code of the CCL program.
