I have a file with varying length records. All but the first record,

segment characters with linefeeds, making a file where each segment is
on its own line.
Hmmmm... here's one way of doing it:
import mmap
import sys
DELIMITER_OFFSET = 107
N.B. this is a zero-based 107. If you are using one-based coordinates,
then this is actually position 108.
