Editing & greping undelimited data

I find Unix with its line orientation to be only a tiny
bit more advanced than systems that only handle 80-column
card images. I don't understand why the common utilities
can't deal with pure character streams and treat \n the
same as any other character -- that's what Xerox XDE and
ViewPoint/GlobalView do. Instead of dealing with
"lines", just print out a "context" consisting of a
user-specified number of characters on either side of the
search string.
Anyhow, my immediate gripe is: grep doesn't work on
undelimited files. I'd like to be able to use it to
search my XDE mail file table-of-contents files. Those
files consist of fixed-length, undelimited records.
Should I use the perl "read" command to break up these
files with a \n at the end of each record to make grep
work? Any other ideas?
Please copy me by e-mail, as I seldom read this newsgroup.
Thanks,
