6 Customising ASTERIX

Many aspects of ASTERIX's operation can be customised at both the site and user level. This is generally done by supplying extra start up procedures which ASTERIX executes when you type 'aststart' to start a shell or ICL session. These can override the values of built in ASTERIX settings, or define new commands, etc.

A utility called 'astdefs' is provided which displays the important ASTERIX control parameters, eg.

  csh> astdefs

gives the output,

    ASTERIX defaults for user : rb
    Installation
      ASTERIX Version           : 1.7-1
      Installed root directory  : /star/asterix
    Optional Data
      FTOOLS calibration files  : unknown
    Local and user start up procedures
      Site shell start up       : /star/asterix/../ast_local/startup
      Site ICL start up         : /star/asterix/../ast_local/startup.icl
      User shell start up       : UNDEFINED
      User ICL start up         : UNDEFINED
    Logging Info
      Current logging state     : OFF

A fuller listing is available by adding an 'all' argument to the astdefs command.
