The '''SEEK''' statement sets the next byte or record position of a file for a read or write.

:: SEEK ''filenumber&'', ''position''
|
|
|
|
|
|
|
|
* ''filenumber'' must be the file number that is [[OPEN]] and being read or written to.
|
|
* ''position'' is a byte in [[BINARY]] or sequencial files created in [[OUTPUT]], [[APPEND]] or [[INPUT (file mode)]]s. The first byte = 1.
|
|
* ''position'' is the record in [[RANDOM]] files to read or write. Records can hold more than one variable defined in a [[TYPE]].
|
|
* Since the first SEEK file position is 1 it may require adding one to an offset value when documentation uses that position as 0.
|
|
* After a SEEK statement, the next file operation starts at that SEEK byte position.
|
|
* The SEEK statement can work with the [[SEEK]] function to move around in a file.
|
|
|
|
|
|
''Example:'' A SEEK statement using the [[SEEK]] function to move to the next random record in a file.
