Thanks Markus. the interface is ok now, but...

the command line:

v.strahler input=krig_elev_smooth_7x7_streams
output=krig_elev_smooth_7x7_streams_strahler
dem=krig_s4000_r350_pp10_n24 txout=teste sloppy=0.01 layer=1
--overwrite

Error msgs:

GRASS_INFO_WARNING(21038,1): Field number <1> or name <(null)> already exists

GRASS_INFO_WARNING(21038,2): Cannot add database link.
DBMI-DBF driver error:
Table krig_elev_smooth_7x7_streams_strahler already exists
Error in db_execute_immediate()

GRASS_INFO_ERROR(21038,3): Cannot create table: CREATE TABLE
krig_elev_smooth_7x7_streams_strahler ( cat integer, bsnid integer,
sorder integer )

Hello Carlos,
did Markus answer your first mail? I have missed that answer.

Where did you get v.strahler from? I'm asking because the version I
once commmitted to grassaddons svn didn't have the layer option...

Writing to output table was broken (and still is, in my code here).
It should output correct values to the text file, though.
Is there some output in 'teste'?

I'm sorry for not caring for v.strahler in the last months as I had to
focus on other things. I'd like to improve the code but I sure could use
the help of an expert with that table/database code.

Error msgs:

GRASS_INFO_WARNING(21038,1): Field number <1> or name <(null)> already
exists

GRASS_INFO_WARNING(21038,2): Cannot add database link.
DBMI-DBF driver error:

sorder integer )

And I have to catch up on those new error codes :wink:
até amanhã,
\f
