Exactly! I don't want to roll my own. I don't want some "record"
that none of the OS utilities understands. I don't want to have
to invent access routines just so I can rewrite a variable length
record.
On VMS, I can have my records and use them, too! TYPE, for example,
will display any kind of record, without the meta-data, on my
terminal. Yes, it best be printable characters in the data, but I
can see those printable characters without worrying about whether the
record is stream-cr, stream-lf, stream-crlf, variable, fixed, or part
of a keyed indexed file.
I don't have to hope that my text editor is following the same line
separation convention as yours. I don't have to tell the print
spooler which way to parse the file.
And the OS will tell me what meta-data and organisation a file uses
if I ask, instead of hoping the source code is available, or reverse
engineering and hoping I got it right.
Not on bit of which prevents me from using byte stream files when
they are the right tool for the job.
