  The changes since TAOS 7.X are:

    1) White space is added before "(task".
    2) Task has a name, indicated by a subsequent string surrounded by a
       double-quote.
    3) Address expressed in hex number has a preceeding "0x".
    4) Hex numbers are in lower case.
    5) There is a character display corresponding to hex data in each line.
