Programming Errors Section 5-5

Three levels of program checking are available. The desired level must be des- ignated to indicate the type of errors that are to be detected. The following table provides the error types, displays, and explanations of all syntax errors. Check level 0 checks for type A, B, and C errors; check level 1, for type A and B errors; and check level 2, for type A errors only.

Type	Message	Meaning and appropriate response
A	?????	The program has been damaged, creating a non-existent
		function code. Re-enter the program.
	CIRCUIT ERR	The number of logic blocks and logic block instructions
		does not agree, i.e., either LD or LD NOT has been used
		to start a logic block whose execution condition has not
		been used by another instruction, or a logic block
		instruction has been used that does not have the required
		number of logic blocks. Check your program.
	OPERAND	A constant entered for the instruction is not within defined
	ERR	values. Change the constant so that it lies within the
		proper range.
	NO END	There is no END(01) in the program. Write END(01) at the
	INSTR	final address in the program.
	LOCN ERR	An instruction is in the wrong place in the program. Check
		instruction requirements and correct the program.
	JME UNDEFD	A JME(05) instruction is missing for a JMP(04) instruction.
		Correct the jump number or insert the proper JME(05)
		instruction.
	DUPL	The same jump number or subroutine number has been
		used twice. Correct the program so that the same number
		is only used once for each.
	SBN UNDEFD	The SBS(91) instruction has been programmed for a
		subroutine number that does not exist. Correct the
		subroutine number or program the required subroutine.
	STEP ERR	STEP(08) with a section number and STEP(08) without a
		section number have been used incorrectly. Check
		STEP(08) programming requirements and correct the
		program.
B	IL-ILC ERR	IL(02) and ILC(03) are not used in pairs. Correct the
		program so that each IL(02) has a unique ILC(03).
		Although this error message will appear if more than one
		IL(02) is used with the same ILC(03), the program will
		executed as written. Make sure your program is written as
		desired before proceeding.
	JMP-JME ERR	JMP(04) and JME(05) are not used in pairs. Make sure
		your program is written as desired before proceeding.
	SBN-RET ERR	If the displayed address is that of SBN(92), two different
		subroutines have been defined with the same subroutine
		number. Change one of the subroutine numbers or delete
		one of the subroutines. If the displayed address is that of
		RET(93), RET(93) has not been used properly. Check
		requirements for RET(93) and correct the program.
C	COIL DUPL	The same bit is being controlled (i.e., turned ON and/or
		OFF) by more than one instruction (e.g., OUT, OUT NOT,
		DIFU(13), DIFD(14), KEEP(11), SFT(10)). Although this is
		allowed for certain instructions, check instruction
		requirements to confirm that the program is correct or
		rewrite the program so that each bit is controlled by only
		one instruction.
	JMP UNDEFD	JME(05) has been used with no JMP(04) with the same
		jump number. Add a JMP(04) with the same number or
		delete the JME(05) that is not being used.
	SBS UNDEFD	A subroutine exists that is not called by SBS(91). Program
		a subroutine call in the proper place, or delete the
		subroutine if it is not required.
