AA

The DLM parameter assigns the characters AA as the delimiter for the data defined in the input stream by DD statement DD1. For JES2, the characters // would also serve as valid delimiters since a DD * statement was used. JES3 accepts only the characters specified for the DLM parameter as a terminator for DD * or DD DATA.
