I/O Error
Messages
I/O errors are often hard to see. They appear a
white text somewhere on your screen below wherever the cursor was positioned at
the time of the error.
They look a lot like Run-time Error
messages except that the first line says I/O Error xx, PC=nnnn
They are usually generated because some sort of input/output error.
This means that the system was trying to send something to or get something from
a file or output device like a printer.
