BASIC-SO ERROR CODES

Table A-I. BASIC-80 Error Codes

Error		Description	Number

NEXT without FOR	Program contains no corresponding FOR for
	NEXT
SYNTAX ERROR	Illegal usage of delimiters, characters, etc.		2
RETURN without GOSUB_	No GOSUB statement found to RETURN to.		3
Outof DATA	All DATA statements in the program have been		4
	read, or BASIC-80 tried to read too much, or too lit-
	tle data was included in the program.
Illegal function call	Parameter passed to a function was out of range.		5
	Possible reasons:
	1.	A negative array subscript
	2.	An array subscript> 32767
	3.	LOG with a zero or negative argument
	4.	SQR with a negative argument
	5.	AtB with A negative and B not an integer
	6. A call to USR before a corresponding
		DEFUSR
	7. Calls to MID$, LEFT$, RIGHT$, INP, OUT,
		WAIT, PEEK, POKE, TAB, SPC, STRING$,
		SPACES$, INSTR, or ON ... GOTO with im-
		proper arguments
Overflow	Variable with magnitude greater than 3.4E38		6
	(single-precision floating-point) or 1.7D308
	(double-precision floating-point)
Out of memory	Program too large, contains too many loops,		7
	subroutines, variables, or complicated expres-
	sions.
Undefined line number	A referenced line does not exist.		8
Subscript out of range	You referenced an array variable outside the		9
	dimensions of the array, or referenced the wrong
	number of dimensions.
Duplicate Definition	You redimensioned an array previously		10
	dimensioned.
Division by zero	A 'divisionby zero'operation was attempted.		11
Illegal direct	An instruction was used illegally in the Command		12
	Mode.
Type mismatch	A function which expects a string or variable was		13
	given the wrong data type; any improper mix of
	data types.
Out of string space	String variables are larger than the allocated		14
	space. You can increas~ space with CLEAR.
String too long	String exceeds 255 characters.		15
String formula too complex	String was too long or complex; break into two.		16
Can'tcontinue	An attempt was made to continue a program		17
	where an error occurred, or after modifications, or
	with no program.
Undefined user function	Reference to a non-defined USR function.		18
No RESUME	An error trapping routine has no RESUME.		19
RESUME without error	RESUME statement without error-trapping		20
	routine.
Unprintable error	No error message exists for the given error.		21
	Check ERROR statements for undefined errors.
