Handbook 005: Ordered type

Dec
Decrements the data of parameter one, and if there is a parameter two, decrements the parameter
The numerical value as described in Parameter two
Inc
Increment the data of parameter one, if there is parameter two, increment the parameter one
The numerical value as described in Parameter two
Odd
If the callback parameter data is odd, if you want to test if it is an even number,
Directly add a not in front to do the reverse operation can: not ODD
Pred
The previous value of the callback parameter data, the system will be judged according to the parameter type
What should the previous value be?
Succ
The next value of the callback parameter data, the system will be judged according to the parameter type
What should be a value after a set
Ord
The sequence number of the value of the callback parameter in the type (typically used in a non-number
Ordered type of font)
Low
Minimum value in the type of the callback parameter data
High
Maximum value in the type of the callback parameter data
