                         File I/O Error: GetRecordBufferRO() returned a NULL record pointer.  | 
                     
                     
                        
                         CONNX attempted to allocate a read-only I/O record buffer. The function returned a NULL pointer, probably due to a virtual memory shortage or to a non-positive record length.  | 
                     
                     
                        
                         If the error is reproducible, follow procedure A01.  |
