13.1.4 Content and format of the PTT file
Label lists are stored as PTT (protocol translation table) files. The PTT file format is an
extension of the CSV format (comma-separated values). You can edit it with standard
editors, for example, with MS Excel or a text editor.
The PTT file has three types of lines:
●
Comment lines begin with a hash character #. A hash character at any other posi-
tion in the line is treated like a standard character.
●
Command lines begin with a commercial at character @. An @ character at any
other position in the line is treated like a standard character.
●
Standard lines are the lines that not qualify as comment or command lines. They
build the core of the label list.
