Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] strange string behaviour

yes but there is only one cycle because of the turnoff.
so why is it repeating the string?

this code gets the same result although it clearly should only run one 
cycle:
   Snew = ""
   if timeinstk() == 1 then
     Sline = sprintfk("%s%d\n",Snew,1)
     Snew = strcatk(Snew,Sline)
     printf("Sline = \n%s\n",1,Sline)
     printf("Snew = \n%s\n",1,Snew)
   endif

i tried several versions and it has something to do with the line
   Snew = ""

i will try to get closer and then file an issue.
