 10.7 The continue Statement
 ===========================
 
 The ‘continue’ statement, like ‘break’, is used only inside ‘while’,
 ‘do-until’, or ‘for’ loops.  It skips over the rest of the loop body,
 causing the next cycle around the loop to begin immediately.  Contrast
 this with ‘break’, which jumps out of the loop altogether.  Here is an
 example:
 
      # print elements of a vector of random
      # integers that are even.
 
      # first, create a row vector of 10 random
      # integers with values between 0 and 100:
 
      vec = round (rand (1, 10) * 100);
 
      # print what we're interested in:
 
      for x = vec
        if (rem (x, 2) != 0)
          continue;
        endif
        printf ("%d\n", x);
      endfor
 
    If one of the elements of VEC is an odd number, this example skips
 the print statement for that element, and continues back to the first
 statement in the loop.
 
    This is not a practical example of the ‘continue’ statement, but it
 should give you a clear understanding of how it works.  Normally, one
 would probably write the loop like this:
 
      for x = vec
        if (rem (x, 2) == 0)
          printf ("%d\n", x);
        endif
      endfor
