Each file that is attached has an entry in the SYSTABLES file and stored in the @TABLES array. The field layout of these entries is:
Field Number | Description |
0 (key) | File Name. The name by which a user accesses the file |
1 | Volume name. The volume from which this file was attached. This is the volume name as found as an entry in the SYSVOLUMES file. |
2 | True file name. This is different from the key only if this is an aliased table, as set by Alias_Table(). |
3 | Application. The application name to which this file belongs. |
4 | Filing System(s). The MFS/BFS list for that volume (delimited with @VM). |
5 | File Handle. If the file has been opened during this session, the file handle is stored in this field. If the file has not been opened, the next BASIC+ OPEN statement will generate a filing system OPEN.FILE call. |
