C accessMode - Access mode that was set when this unit was opened. |
| 44 |
C Access mode is either read-only or |

C read-write. |
| 46 |
C errorMode - Error mode that was set when this unit was opened. |
| 47 |
C Error mode is either STOP on error which means the |
| 48 |
C program halts or continue or error. For continue |
| 49 |
C error the program usually tries to write an error |
| 50 |
C message to stderr. Howeever, the most common cause for |
| 51 |
C an IO error is a full disk in which case that |
| 52 |
C error message may be lost! |

C associated with a file that is opened. |
| 55 |
C theErrorMode - The current error mode. This will be the mode |
| 56 |
C associated with a file that is opened. |
