omg got it in native of strins
format(par1, sizeof(par1), "<%s>", par1); strins(string, par1, strlen(string)+1);

i change to
format(par1, sizeof(par1), "<%s> ", par1); strins(string, par1, strlen(string));

it work fine

so how about

format(par1, sizeof(par1), "<%s>", par1); strins(string, par1, (strlen(string)+1));
