A..0.0.2 Binary format

The MESH and SOL can be written in binary. It is also based on keywords but those last are given with numbers. The correspondance table between numbers and keywords are given as follows:

Thus the file must begin with the integer $1$ which has been followed by the version number (1 for simple précision, 2 for double précision).

Next, there is the integer $3$ (Dimension) then an integer corresponding to the file position at the end of the information concerning the dimension, i.e. after the integer indicating the dimension (so it is the number $20$: an integer is stored on 4 bits and including this one, we will write five integers) then the space dimension (2 or 3).

The continuation of the file is composed by other keywords with the following convention: just after the keyword number, you have to indicate the file position at the end of the information concerning this keyword then you give this information.
