Seek

Sets the current position within a file opened using the Open statement, ready for the next read or write action.

The required FileNum argument must contain an Integer representing any valid system file number associated with an open file.

The required Position argument must contain an Integer or expression representing a valid number.

Note: The file system keeps track of all open files and the current position of access within every file. Every statement or function that accesses the data within a file, alters the current position within that file. The Loc function can be used to determine the current position within an open file.
