Data files on a multi-user system, like Autoline, while being accessed in read-write mode when creating or modifying records, have their in-use flag set to prevent similar access by another user. Such file-locking prevents more than one user simultaneously attempting to alter a file, and one overwriting the other's modifications when he/she saves it. Depending on the module and/or file, locking may be of the whole file or only of its record(s) open for read/write.
Note: In-use flags are reset automatically in the end-of-day procedure timed operation.
A problem arises when, because of, for example, power failure or oversight, a user's terminal shuts down without relinquishing a file's or a record's in-use flag. The file or record is then inaccessible by other users who may need to update it.
To reset a file's or a record's in-use flag:
