Ok, sorry for boing unclear. A new try:

I want to store the command line, which was used to start a
module, into the history section of data.

Example: I run

r.proj dgm1km loc=europa map=europa
When I now run

 r.info dgm1km

the string "r.proj dgm1km loc=europa map=europa" should appear in
the history. This is implemented in r.slope.aspect and s.surf.rst,
but more complicated there. For my module (not r.proj) the command line
string is sufficient to later remember the parameters which I used to
generate that particular map.

It must be something with argv[] or so.

Thanks,

 Markus
