====== The SYSTABLES File ======

Each file that is attached has an entry in the SYSTABLES file and stored in the [[environment|@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|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|OPEN statement]] will generate a filing system [[open.file_call|OPEN.FILE]] call.|
