This way it works, had to put that option and constrain vector both into the input parentheses:
Now I get no division by 0 warning. The previously miss-specified-due-loss-of-precision point's are now not specified at all and the value is substituted by 0.14 but the error isn't likely big.
start mincvf(CVF1);
con={0.14 . .,. . .,. . .};
optn={0,0};
init=1;
call nlpqn(rc, res,"CVF1",init,optn,con);
return (res);
finish;
Thanks for the help!
