What options are there for using delimiters?
It is preferable to use the tilde (~) character. For queries or reports, you can use either the tilde or the null character as delimiters to separate the fields. If the query is null delimited, then the response will contain null delimiters, whereas queries with tilde delimiters will have responses that have the tilde delimiters. For the Continuous Query service (formerly know as PDS), all submissions and responses must be tilde-delimited.
