with regard to azimuth tag

Dear GNU Gama professionals,

I would like to use new azimuth feature, trying to combine masurements made with theodolith and laser distance meter or with compass, miner's level and laser distance meter.

I compiled GNU Gama 1.14 with mingw on windows xp.

Now it seems to me that GNU Gama simply ignores the azimut values. 

For all points defined by azimuth values instead of directions GNU Gama's seems to ignore the input.

Trying the appended Azimut_Test1.gkf - Intended as an equilateral triangle with two fixed points "1" an "2" and one new point ("3"-"9") measured in differend ways - I will get "Missing coordinates" in the output. 

May be I have a wrong understanding of the concept behind the azimuth implementation?

In the manual I find "<azimuth from="1" to= "2" val= "96.484371" />" as an example. The "from =" part is not accepted by the software. 

I find the File "gama-local.dtd" in \gama-1-14\xml\ defines no "from ="

<!ATTLIST azimuth
   to       CDATA    #REQUIRED
   val      NMTOKEN  #REQUIRED
   stdev    NMTOKEN  #IMPLIED
   from_dh  NMTOKEN  #IMPLIED
   to_dh    NMTOKEN  #IMPLIED  > 

so the azimuth statement is to be nested in an "obs from =" statement?

In the manual page 12 in the PDF version I read

" The value of an orientation angle can be explicitly stated with an attribute orientation="...". Normally, it is more convenient to let the program calculate approximate values of orientations needed for the adjustment. If directions are present, then the attribute station must be defined. "

Am I right in thinking that "orientation" is not the same as azimuth? Orientation may be used finding approximate coordinates and directions as starting point and azimuths are used only in the adjustment?
Is the mentioned "attribute station" to alter in the "from =" part of "obs" like in the examples?

Thank you in advance for any further information.

Dirk
