... data3.1
Programmers are always free to choose any format they like in memory - this is usally hidden from the users. What we mean here is the disk format. The popular memory (object) models, and how they interact with persistent data on disk, are discussed in Chapter [*]

...hisf. 3.5
HISTORIC NOTE: To prevent data files having a history written into them an environment variable HISTORY must be set to 0. This dates back from older times when not all programs could properly handle data files with embedded history items properly. Also note there is no associated system keyword with HISTORY. It is expected that this feature will disappear, i.e. history is always forcefully written into the data files, unless the user interface (getparam.o in libnemo.a) was explicitly compiled with the HISTORY disabled.
