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.
