The named counter fields
Each named counter consists of the counter name, the current value, the minimum value, and the maximum value.
- The counter name
- The name can be up to 16 bytes, comprising the characters A through Z, 0 through 9, $ @ # and _. Names less than 16 bytes should be padded with trailing blanks.
- The current value
- The next number to be assigned to a requesting application program.
- The minimum value
- Specifies the minimum number for a counter, and the number to which a counter is reset by the server in response to a REWIND command.
- The maximum value
- Specifies the maximum number that can be assigned by a counter, after which the counter must be explicitly reset by a REWIND command (or automatically by the WRAP option).
