Used by the routines at CheckBitAndProcess and InspectActionTakenFlag.
Advances the entry with AdvancePointerAndCheckBit and returns zero when InspectActionTakenFlag rejects it. Keeps going while bit 3 of the action flags is clear.

|
Advance pointer and check bit.
|

| CheckBitAndProcessEntry | BF08 | CALL AdvancePointerAndCheckBit | Call AdvancePointerAndCheckBit to advance the pointer and test the bit. | |
| CheckBitAndProcessEntry_Loop | BF0B | BIT 3,(IX+$03) | See whether bit 3 of it is set, then call InspectActionTakenFlag to run entry with counter. | |
| BF0F | PUSH AF | |||
| BF10 | CALL InspectActionTakenFlag | |||
| BF13 | JR NZ,CheckBitAndProcessEntry_Next | Jump ahead to CheckBitAndProcessEntry_Next when the entry counter is still running. | ||
| BF15 | POP AF | |||
| BF16 | XOR A | Clear A. | ||
| BF17 | RET | Return. | ||
|
Return.
|
||||
| CheckBitAndProcessEntry_Next | BF18 | POP AF | Restore the bit test from the stack. | |
| BF19 | JR Z,CheckBitAndProcessEntry_Loop | Go back to CheckBitAndProcessEntry_Loop if bit 3 is clear. | ||
| BF1B | RET | Return. | ||
