Type a prefix value in the SAS/C TCP/IP prefix value field to set a prefix value.
This parameter is used to set the value of the SAS/C environment variable =TCPIP_PREFIX. A value of DEFAULT indicates that ISPF should set no value. If a non-blank value is specified, SAS/C concatenates that string to the characters .TCPIP.DATA. For example, specifying a value of TCPIP causes SAS/C to search for the data set TCPIP.TCPIP.DATA.
The default is DEFAULT.
