Halcon - initialize tuple of iconic variables

How can I initialize a empty tuple of iconic variables?

I am trying to do this:

        concat_obj(AllStr, Str, AllStr)

AllStr is not initialized, so it throws an exception..

Solution

  • The object needs to be initialsed first using gen_empty_obj(str) The code would look like this then,

    gen_empty_obj(str) 
gen_empty_obj(AllStr)
str := iconic_object_1
AllStr := iconic_object_2
concat_obj(AllStr, str, AllStr)
