FieldTypeComment
ActionCallACTIONRECORDHEADERActionCode = 0x9E

ActionCall does the following:

  1. Pops a value off the stack. This value should be either a string that matches a frame label, or a number that indicates a frame number. The value can be prefixed by a target string that identifies the movie clip that contains the frame being called.
  2. If the frame is successfully located, the actions in the target frame are executed. After the actions in the target frame are executed, execution resumes at the instruction after the ActionCall instruction.
  3. If the frame cannot be found, nothing happens.
