The POSITION specifier indicates the position of a file connected for sequential access. It takes the following form:
| 'ASIS' | Indicates the file position is unchanged if the file exists and is already connected. The position is unspecified if the file exists but is not connected. |
| 'REWIND' | Indicates the file is positioned at its initial point. |
| 'APPEND' | Indicates the file is positioned at its terminal point (or before its end-of-file record, if any). |
The default is 'ASIS'. (On Fortran I/O systems, this is the same as 'REWIND'.)
A new file (whether specified as new explicitly or by default) is always positioned at its initial point.
