an integer specifying
the number of bytes that need to be back from the end of the file.
Specifying a 0 means the end of the file. This parameter can be specified
as a number, field name, or expression.
Details
The SEEKEND method moves
the file pointer backward the number of bytes that were specified,
where 0 indicates the end of the file. It returns true on success
otherwise false is returned.
Example
file f
f.open("C:\filename.txt", "rw")
// write information to the end of the file
f.seekend(0)
f.writeline("This is the end ")
f.close()
