Issues with using PUT and width specifications

An extremely interesting point was brought up by Chang Chung about the length of the variable when it is used with a put function.

/* center a char vars with -c format modifier */
data one;
      /* ----+----1- */
  var = "          x";  
  centered = put(var, $10.-c);
/* check */
proc print data=one;
/* on lst -- surprise, just blanks!
Obs    var    centered
  1     x
