7.3.1 Punched tape format
1. Only files with displayable characters, i.e. files set up in the text
editor, can be saved in this format. Binary data is excluded.
2. Files in punched tape format can be edited with the text editor.
3. Files can be set up externally in punched tape format provided that
they are formatted in compliance with the format specified below.
4. If a file is set up manually, it must begin with %<name>, "%" must
be typed in the first column of the first line. An archive in punched
tape format may contain several files, each of which must begin
with %<name>.
The structure of archive files in punched tape format is as follows:
<Leader> ;can be included
%<File name 1>
;$PATH=<Path name 1> ;can be included
1st block
L
F
;contents of file 1
2nd block

<Leader> Information of any type (characters with ANSI values < ANSI value 32
(blank)) which is not part of the useful data on the punched tape.
They might be positioned at the beginning of the tape so that it can be
inserted into the punched tape reader.
When the archive file is read, a check is made to determine whether it
was saved with a leader. If it was, then it is read in again with a
leader.
LF

Character for end of block/new line; ANSI value 10 (0x0A)
ANSI value 13 (0x0D)
