From the documentation The values for WHENCE are 0 to set the new position in bytes to POSITION; 1 to set it to the current position plus POSITION; and 2 to set it to EOF plus POSITION, typically negative. I suspect your error message is because you are trying to `seek` to a negative offset from the beginning of the file. Cheers, JohnGG	[reply] [d/l]

`seek (file, distance, from)` As you can see, seek requires three arguments: file: which is the file variable representing the file in which to skip distance: which is an integer representing the number of bytes (characters) to skip from:which is either 0, 1, or 2 0 - The number of bytes to skip from beginning of the file. 1 - The number of bytes to skip from current location of the file. 2 - The number of bytes to skip from end of the file. `seek(CONFIRMEDOUTPUTFILE, -500, 2);` The above line skip backward 500 bytes from the end of the file.
