Question: I am getting the Cicode general hardware error 'Out of buffers'. What is the most likely cause of this error? 

The error 'Out of buffers' can be generated by in the following ways:

1). Calling QueWrite() and the queue functions have run out of buffers. You can increase the number of queue buffers with the option [Code] Queue.

2). Calling WinFree(), where you will free the last Cicode window. If WinFree did free the window, then Citect would have no windows left.

To verify which function is causing the hardware error, display the {ERRPAGE} and {ERRDESC} fields on the hardware alarm.
