Code DLCADDR for switched connections where the DLUS host can call out to a remote physical unit that is supported by a DLUR. The information that is coded on the DLCADDR operand is dictated by the DLUR being used. Refer to the DLUR implementer documentation (README file) or to the z/OS Communications Server: SNA Network Implementation Guide for information on how to code the DLCADDR contents. The DLUR implementer is responsible for verifying the contents of the DLCADDR operand.
