BASIC 3.5 Error Messages 397
11 SYNTAX ERROR
This message indicates that you have not followed the BASIC syntax rules.
Check the command to see if you misspelled a BASIC keyword, typed a non-
BASIC word without enclosing it in quotes or placing it in a REM statement,
added something to a command that is not allowed, omitted something required
in a command, or used an odd number of parentheses.
IS RETURN WITHOUT GOSUB
RETURN commands must always accompany GOSUB commands. This mes
sage indicates that BASIC found a RETURN command when a GOSUB was not
currently executing.
13 OUT OP DATA
This message indicates that the current READ command cannot find a DATA
value because no DATA command exists or all the DATA values have been read
previously. Although it is legal to have excess DATA values in a program, all
READ variables must be matched to DATA values. You can use the RESTORE
command to reREAD DATA.
14 ILLEGAL QUANTITY
This message indicates that the current command or function parameter contains
a number that is outside the legal range for the circumstances. For example, the
first parameter in a COLOR command, color source, can be 0-4, so COLOR
6,1,2 results in an ILLEGAL QUANTITY error.
15 OVERFLOW
This message indicates that the result of the current calculation is a number with
absolute value greater than 1.701411833E+38, which is the largest legal number in
BASIC 3.5.
16 OUT OP MEMORY
This message indicates that the current program is too large for the available
RAM, or that the program contains too many DO, FOR, or GOSUB commands,
or that the program contains DO commands with no LOOP or EXIT command,
or GOSUB commands with no RETURN command. This error can also be
caused by repeated assignments to the same string variable; a call to the FRE
function may correct this problem.
