EC4C: Show a carried thing in the panel's box
Used by the routines at PICK_UP_LOOK_ON and MAIN_LOOP.
The author's INFOR (named by its calls in the leftover source text). Clears the panel's box and prints the number of the carried place in use (CLEAR_THING_BOX), then draws the sprite of the object whose record is at HL in the box, at x 20, row 40: only the sprite's image, with the compositor's first two planes cleared, over what the box holds. Called when a thing is picked up (PICK_UP_LOOK_ON) and when a carried place that holds one is chosen (MAIN_LOOP).
