So, if you know how to use a chisel but not a screwdriver, you'd rather use the chisel to remove a screw from your antique? BTW I learned to program in FORTRAN in 1965 - these days I make my living designing/coding in C++, and I may have to learn something new before I get around to retiring. One unchanging truth about computing is that it changes continually, which is good because we continually get new tools to solve problems more efficiently, but bad because you don't get much opportunity to rest on your laurels.
