Parameters and prompts

Most of the information required by ECHOMOP from the user is obtained using the FIGARO parameter system. This standard method of obtaining values leads to a consistency of user interace between all FIGARO based tasks. However in some cases it is more convenient to present the user with a menu of choices and this approach is used for the top level selection of processing steps , and also during interactive graphics intensive steps.

When a FIGARO parameter is prompted for, the default value is indicated enclosed in [ ] brackets. As well as entering a value the user may also use the following special responses which are processed by the FIGARO parameter system :

• ? provides information on parameter type, minimum and maximum allowed values etc.

• ?? provides same information as above plus any detailed help text available.

• !! requests an abort of the task

• Backslash causes all subsequent parameters to adopt their default values without further prompts.
