In it’s simplest form, Command-LogiX reads an ASCII text file (in a specific format) which contains two or more call points and outputs a new file giving the time and distance taken to travel the whole journey. Place names can be entered as:
Postcode or Zipcode.
Latitude/Longitude co-ordinate.
Ordnance Survey Grid Reference (valid only in the UK).
Non-ambiguous place name.

This last option needs a little further explanation. Command-LogiX will recognise a valid Postcode or numeric co-ordinate. Any other entry will be checked against the extensive internal Gazetteer in an attempt to determine its location. Place names that occur more than once in a database need to be reinforced by the appropriate county or region name. As an example, the name 'Leeds' appears more than once in the British database, so using this name by itself would not be sufficient for a unique location. However 'Leeds, West Yorkshire' renders the address unambiguous. The routine is fairly intelligent, and would also recognise 'W.Yorkshire' and 'Yorks' as valid county names.
