Populated by CountDuplicates.
Used by the routine at CalculateHand.

|
Table_CardDuplicates holds counts of duplicate values of cards, this routine specifically looks for four-of-a-kind matches.
|
||||
| Handler_FourOfAKind | 94AA | LD HL,$9540 | HL=Table_CardDuplicates. | |
| 94AD | LD B,$0D | Set a counter in B of the number of possible values of cards there are in one suit. | ||
|
There's no need to check any further if there's a match, as if there are 04 of any card value, there are only 05 cards in one hand - so there can't be a second match.
|
||||
| Handler_FourOfAKind_Loop | 94AF | LD A,(HL) | Return if *HL is equal to 04. | |
| 94B0 | CP $04 | |||
| 94B2 | RET Z | |||
| 94B3 | INC HL | Increment HL by one. | ||
| 94B4 | DJNZ Handler_FourOfAKind_Loop | Decrease counter by one and loop back to Handler_FourOfAKind_Loop until counter is zero. | ||
| 94B6 | INC B | Increment B by one. | ||
| 94B7 | RET | Return. | ||
