Robotron: 2084: Routine at 36498

36498: Print Handler: Tab

TAB parameter handler. Called on the byte immediately following a 23 (TAB) control code. Sets the X position (32769) to the parameter value. If the parameter is less than the current X position (i.e., the cursor would move left), the Y position advances to the next row.
PrintHandler_Tab	36498	LD HL,36323	Reset PrintState_Handler to PrintHandler (default handler).
	36501	LD (32778),HL	Reset PrintState_Handler to PrintHandler (default handler).

	36508	LD B,A	B=*PrintState_X (current X position).
	36509	LD A,C	A=target X; write target X to *PrintState_X.
	36510	LD (32769),A	A=target X; write target X to *PrintState_X.
	36513	SUB B	A=target X − current X.
	36514	RET NC	Return if the cursor moved right or stayed (no row advance needed).
	36515	LD HL,32768	HL=32768 (Y position pointer).
	36518	CALL PrintHandler_AdvanceRow	Call PrintHandler_AdvanceRow to advance the Y position by one line.
