lOAD There is a problem with the program on tape.
NEXTWITHOUTFOR This is caused by either incorrectly nesting loops
or having a variable name in a NEXTstatement that doesn't correspond
with one in a FOR statement.
NOT INPUTFilE An attempt was made to INPUTor GET data from a
file which was specified to be for output only.
NOT OUTPUTFILE An attempt was made to PRINTdata to a file which
was specified as input only.
OUT OF DATA A READ statement was executed but there is no data
left unREAD in a DATAstatement.
OUT OF MEMORY There is no more RAM available for program or
variables. This may also occur when too many FOR loops have been
nested, or when there are too many GOSUBs in effect.
OVERFLOW The result of a computation is larger than the largest
number allowed, which is 1.70141884E+38.
REDIM'DARRAY An array may only be DIMensioned once. If an array
variable is used before that array is DIM'd, an automatic DIM operation
is performed on that array setting the number of elements to ten, and
any subsequent DIMs will cause this error.
REDO FROM START Character data was typed in during an INPUT
statement when numeric data was expected. Just re-type the entry so
that it is correct, and the program will continue by itself.
RETURNWITHOUT GOSUB A RETURNstatement was encountered,
and no GOSUB command has been issued.
STRINGTOO lONG A string can contain up to 255 characters.
?SYNTAX ERROR A statement is unrecognizable by the Commodore
64. A missing or extra parenthesis, misspelled keywords, etc.
TYPEMISMATCH This error occurs when a number is used in place of a
string, or vice-versa.
UNDEF'D FUNCTION A user defiried function was referenced, but it
has never been defined using the DEF FN statement.
UNDEF'D STATEMENT
An attempt was made to GOTO or GOSUBor
RUN a line number that doesn't exist.
VERIFY The program on tape or disk does not match the program cur-
rently in memory.
