#endinitclip
Description
The #endinitclip pragma ends a special block of code (begun with #initclip) that initializes a movie clip symbol before any instances of it are created. It can appear only on frame 1 of a movie clip symbol (it causes a compile-time error elsewhere) and must be preceded by #initclip. For complete details, see #initclip.
