Unlock
Removes a previous access restriction (lock) on a file
Syntax
`
Unlock #filenum, record
Unlock #filenum, start To end
`
Parameters
`filenum`
The file number used to `Open` the file.
`record`
The record (`Random` files) to unlock.
`start`
The first byte position (`Binary` files) in a range to unlock.
`end`
The last byte position (`Binary` files) in a range to unlock.
Description
`Unlock` removes the temporary access restriction set by `Lock`.
It is strongly recommended to use the same arguments used in the previous `Lock`.
Note: This command does not always work, neither as documented nor as expected. It appears to be broken at the moment.
Example
For an example see `Lock`.
Differences from QB

- Currently, FB cannot implicitly unlock the entire file
- In `Random` mode, FB cannot unlock a range of records
