<b>Size Macros</b>
|
|
|
|
The following size macros (SIZE_NDLTYPE_ACPRIO through SIZE_BYTE)

cannot be changed without breaking DCC compatibility. The sizes are in number
|
|
of bits.
|
|
|
|
For each of the types, one additional bit is allocated. This
|
|
leftmost bit is used to indicate that the value is invalid.
