Environment variables

catremote takes some input from Unix shell environment variables and these variables can be used to control its behaviour. Some of the variables are optional, but others are mandatory and must be set before catremote is invoked. Default values are set when CURSA is started. All the environment variables used are listed in Table , though the only ones that you are likely to need to change are CATREM_CONFIG and CATREM_MAXOBJ, which are described briefly below. For a complete description see SSN/76[11].
