cmMaintStatsDelimiter is a read-write single-character display string setting the delimiter character inserted between columns in statistics files the system uploads, defaulting to the pipe character. An administrator changes this if their downstream processing tools expect a different delimiter, such as a comma, instead of the default pipe. For example, an operator whose reporting scripts parse comma-separated values would set cmMaintStatsDelimiter to ',' so uploaded statsAuto files match that expected format.
