The maximum host name length that TP1/Client can handle is 63 characters. However, you can use the host name extension function to extend the host name length to a maximum of 255 characters. To use the function, specify 00000008 (logical addition) in DCCLTOPTION in the client environment definition.

The header file dcvclt.h provided by TP1/Client defines MAXHOSTNAME (=64) and DCMAXDNSNAME (=256). Use these definitions as required when creating a CUP.
