  20 /*  FUNCTION
  21         Copy a string. Works like an assignment "dest=src;". At most
  22         n characters are copied.
  23
  24     INPUTS
  25         dest - The string is copied into this variable. Make sure it is
  26                 large enough.
  27         src - This is the new contents of dest.
  28         n - How many characters to copy at most. If the string src is
  29                 smaller than that, only strlen(str)+1 bytes are copied.
  30
  31     RESULT
  32         The number of copied characters.
  33
  34     NOTES
  35         No check is made that dest is large enough for src.
  36         SAS/C specific.
