Number Section, containing the values of all of the numeric capabilities, each as a short integer String Section, containing short integer offsets into the String Table, one per string capability String Table, containing the actual characters of the string capabilities. NOTE that all short integers in the file are stored using VAX/PDP-style byte-order, i.e., least-significant byte first. There is no structure definition here because it would only confuse matters. Terminfo format is a raw byte layout, not a structure dump.
