This tells you that the error is on line 9.
As you can tell from above.  That line tries to read from the file
you opened for reading!

>bad file number (-1)
This file number is file number that was returned.
If you look in the documentation you will notice that -1 means
that it failed to open the file.
NOW you may have a share / lock problem associated with
Windows OR
MOST likely you simply specified the wrong path or file name.

As you can see here again. You were using b as the file handle
for the file you were going to read in. Again the value of b is -1.
This states that there was an error in opening the file.
