Error Message
ILLEGAL DIRECT
ILLEGAL OUANTITY
NEXT WITHOUT FOR
OUT OF DATA
Cause and Suggested Remedies
A command was given in immediate (direct)
mode that is valid only in program mode. The
following are invalid in immediate mode:
DATA. DEF FN. GET. GET#. INPUT. INPUT#.
Enter the desired operation as a (short) pro-
gram and RUN it.
A function is passed one or more
parameters that are out of range. This
message also occurs if the USR function is
referenced before storing the subroutine ad-
dress at memory locations 1 and 2.
Check the ranges given in Chapter 4 for the
function in question. Change the program to
be sure that the argument will always be with-
in range. or add a check before the fu netion
reference to make sure that the argument is
allowed. If USR error. insert statements to
POKE the subroutine address before the USR
reference.
A NEXT statement is encountered that is
not tied to a preceding FOR statement. Either
there is no FOR statement or the variable in
the NEXT statement is not in a corresponding
FOR statement.
The FOR part of a FOR ... NEXT loop must
be inserted or the offending NEXT statement
deleted. Be sure that the index variables are
the same at both ends of the loop.
A READ statement is executed but ail of the
DATA statements in the program have already
been read. For each variable in a READ state-
ment. there must be a corresponding DATA
element.
Add more DATA elements or restrict the
number of READs to the current number of
DATA elements. Insert a RESTORE statement
to reread the existing data. Or add a flag at the
end of the last DATA statement (any value not
used as a DATA element may be used for the
flag value) and stop READing when the flag
has been read.
