SEEK (statement)

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

Syntax

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.

SEEK 1, SEEK(1) + 1
