The SEEK function returns the current byte or record position in a file.

Syntax

byte = SEEK(filenumber&)

• Filenumber is the number of an OPEN file in any mode.
• In RANDOM files SEEK returns the current record position.
• In BINARY or sequencial files SEEK returns the current byte position(first byte = 1).
• Since the first file position is 1 it may require adding one to an offset value when documentation uses that position as 0.
• Devices that do not support SEEK (SCRN, CONS, KBRD, COMn and LPTn) return 0.
