1 U n e x p e c t e d N E X T
A NEXT command has been encountered while not in a FOR loop, or the control variable in the
NEXT command does not match that in the FOR.
2 S y n t a x E r r o r
BASIC cannot understand the given line because a construct within it is not legal.
3 U n e x p e c t e d R E T U R N
A RETURN command has been encountered when not in a subroutine.
4 D A T A e x h a u s t e d
A READ command has attempted to read beyond the end of the last DATA.
5 I m p r o p e r a r g u m e n t
This is a general purpose error. The value of a function' s argument, or a command parameter is
invalid in some way.
6 O v e r f l o w O v e r f l o w
The result of an arithmetic operation has overflowed. This may be a floating point overflow, in which
case some operation has yielded a value greater than 1.73-38 (approx.). Alternatively, this may be
the result of a failed attempt to change a floating point number to a 16 bit signed integer.
7 M e m o r y f u l l
The current program or its variables may be simply too big, or the control structure is too deeply
nested (nested GOSUBs, WHILEs or FOR).
A MEMORY command will give this error if an attempt is made to set the top of BASIC' s memory
too low, or to an impossibly high value. Note that an open cassette file has a buffer allocated to it,
and that may restrict the values that MEMORY may use.
8 L i n e d o e s n o t e x i s t
The line referenced cannot be found.
9 S u b s c r i p t o u t o f range
One of the subscripts in an array reference is too big or too small.
1 0 A r r a y a l r e a d y d i m e n s i o n e d
One of the arrays in a DIM statement has already been declared.
1 1 D i v i s i o n b y z e r o
May occur in Real division, integer division, integer modulus or in exponentiation.
1 2 I n v a l i d d i r e c t c o m m a n d
The last command attempted is not valid in Direct Mode.
