another file input problem

Does anyone know how to start reading information from a txt file from a location (which would be in the form of a saved LOC)

eg open "txtfile1"for outpur as #1
open "txtfile2 for output as #2
write #2, LOC(1)

This would save the current byte location of txtfile 1, but how could I start inputting from that location some other time??? thnx.

Open as binary. The documentation shows how to read from a
sequential file as binary...which is essentially one character at a
time. There is probably a better way to do it, maybe involving
Get and PUT, but I don't know them right off hand.
