Many of the programs use menus to find out what the user requires next. When a menu-type prompt is given, the answer may be abbreviated, as long as a unique match is achieved (in many cases the most abbreviated form is given in brackets). Some menus also allow numbers or additional strings to follow (or even replace) the menu options themselves.
The menu parser can accept the command ``%'' to alter the prompting style. At present can be from 0 (no menu, just menu name) to 3 (full menu, abbreviations given in square brackets). This will then apply to future calls of the menu routine (note that the parameter menus (e.g. ARC_OPTS) are dealt with separately to most of the menus, and only support option 2. Options 0 and 1 are for experienced users, especially if they are working with slow terminal lines (or slow computers!). The formats are as below:
Edit options  -

For options 1 and 2 the minimum abbreviation is given in upper case.
