Spectrum ROM: Routine at 1BB3

1BB3: THE 'LINE-END' ROUTINE

Used by the routines at STMT_LOOP, STMT_NEXT and IF_CMD. The routine at REM continues here. If checking syntax a simple return is made but when 'running' the address held by NXTLIN has to be checked before it can be used.
LINE_END	1BB3	CALL SYNTAX_Z	Return if syntax is being checked; otherwise fetch the address in NXTLIN.
	1BB6	RET Z
	1BB7	LD HL,($5C55)
	1BBA	LD A,$C0	Return also if the address is after the end of the program - the 'run' is finished.
	1BBC	AND (HL)
	1BBD	RET NZ
	1BBE	XOR A	Signal 'statement zero' before proceeding.
This routine continues into LINE_USE.
