I'm guessing you're reading a file and tried to read more data than the file provided. If so, try using LOF(#handle) to determine the length of the file before reading. You could also use a LOOP UNTIL EOF(#handle).

Just guessing though.

I'm READing DATA statements internal to the program to populate some arrays. I have checked and re-checked the READ/DATA statements to make sure the number of data statements, the variables being read, and the array dimensions all match-up. I'm thinking that's not really the error. The parser has read way past that point in the program and encountered some other situation it cannot resolve. I'm going back to verify all the flow controls being used.

It may help to include an end "key" in the data, like "END" or 0, then add an IF..THEN that looks for it after the READ and then stop reading data.

for n = 1 to 5
read n$
print n$
if n$ = "end" then exit for
next n
DATA "1", "2", "3", "end"

Try running program with Lite Debug (Run\LiteDebug or Ctrl-F5)
On error it will open debugger, showing error line.
You may figure something out from variables in top pane

If it all matches up and your arrays are filled correctly then I suspect you are dropping into the data reading code block more than once. So yes check program flow.
