This will be restored back into HL by the end of the routine.

| 41207 | PUSH HL | Stash HL on the stack temporarily. | ||
| 41208 | LD L,(IX-2) | L=*IX-2. | ||
| 41211 | LD H,(IX-1) | H=*IX-1. | ||
| 41214 | LD A,L | Is HL zero? | ||
| 41215 | OR H | |||
|
Pretty clever way of using the stack here.
|
||||
| 41216 | EX (SP),HL | Swap the *SP with the object pointer, restoring HL to the original value. | ||
| 41217 | POP IX | Restore the object pointer into IX (from the stack). | ||
| 41219 | RET | Return. | ||
