CICS record based channel containers/queues

CICS should support an alternative or enhancement to channel containers that is record based rather than byte based. These would be similar to temporary storage queues, except they would have the same visibility and lifetime rules as any other channel containers.

My thought is that the term QUEUE would be used in a similar manner as CONTAINER, but that is not a requirement as such.

The following are the specific requirements:
- This new feature (queue or whatever) would be attached to a channel in a manner similar to how containers are created and accessed (PUT, GET, DELETE, MOVE, etc.)
- Should support variable length records
- Should support full-word record lengths
- Should support full-word record numbers
- Should have the ability to append a new record to the end of the queue
- Should have the ability to rewrite/update an existing record (even if the record length is different)
- Should have the ability to specify a specific record number, or to read the next record
- Should have the ability to query on the number of existing records
- Should have the ability to query on the length of an existing record
- Should support a NODATA option
- May support code page conversion for CHAR records

Notes:
- I use the term “record” instead of “item”, but they are both really the same thing.
