A18A: Store That Byte In The Link Ahead
Used by the routine at AllocateMemory.
Store that byte in the link ahead of this record, then exchange the source with the pointer.
StoreThatByteLinkAhead A18A LD (IX-$02),L Store the pointer in the previous memory entry.
A18D LD (IX-$01),H
A190 EX DE,HL
A191 ADD IX,DE Step to the next memory entry.
This entry point is used by the routine at AllocateMemory.
StoreThatByteLinkAhead_TestBytePreviousMemory A193 INC IX Store this byte in the previous memory entry and take its address.
A195 LD (IX-$03),C
A198 PUSH IX
A19A POP HL
A19B DEC HL Point HL at the two bytes before this record.
A19C DEC HL
A19D LD B,C Copy the count into B.
A19E DEC B Drop one from that count.
A19F XOR A Clear A so the following loop writes zeros.
StoreThatByteLinkAhead_CountEntryRepeat A1A0 LD (HL),A Count the next entry and repeat from StoreThatByteLinkAhead_CountEntryRepeat.
A1A1 INC HL
A1A2 DJNZ StoreThatByteLinkAhead_CountEntryRepeat
A1A4 OR $01 Reset the zero flag.
A1A6 POP BC Restore the saved registers from the stack.
A1A7 POP DE
A1A8 POP HL
A1A9 POP IY
A1AB RET Return.
This entry point is used by the routine at AllocateMemory.
Join the next step.
StoreThatByteLinkAhead_JoinStep A1AC JP Error_OutOfMemory Jump to Error_OutOfMemory, the out of memory.
