The TenDRA project included development of TDF, which is AFAIK more or
less ANDF.

I don't know of any TenDRA development anymore, but the data is still
available, including the TDF 3.x and 4.0 specs.

They have also a guide to the specification, which gives an overview.

Anyway, if undestand this right I find this strange. For example they want the translator not to make assumptions about the target machine, like about the number of bits in an long. But this means to me, that a C compiler should compile this in any case:

char x[sizeof(long)-3];

because he has no idea about the size of long. In C++ the situation is even more complicated, becase sizeof(long) could be used to select an explicit template specialization, resulting in completely different code for different wordsizes.

This could be done, but would lead to the situation that semantic errors could occur during the assembly of an application.

I will probably need to read that again.
