Subject: Re: bug sscanf when match fails ?
Cc: djgpp AT delorie DOT com

I too have found the sscanf bug and have had to use this instead:

        sscanf(" %s %s %s ",a1, a2, a3, a4);
        strcpy(words,a1);
        Bdata = atof(a2);
        Cdata = atoi(a3);
        Ddata = atol(a4);

A real kludge if you as me :(.
