Configuration Parameters

Dyalog can be customised using configuration parameters. These can be set in various ways; if a configuration parameter is set in multiple places the following descending order of precedence applies:

  1. command line settings
  2. application configuration file settings
  3. environment variable settings
  4. user configuration file settings
  5. built-in defaults

This provides a great deal of flexibility, enabling a user to override one setting with another. For example, a "usual" workspace size (MAXWS) can be defined in the user configuration file, but be temporarily superseded by entering a different value when starting a Dyalog Session from the command line.
