They can be customised to the purchaser’s requirements by: • hiding the standard menus and toolbars • creating new menus or toolbars with just the essential requirements • making decorative changes to the colour scheme and logo †¢ creating macros run by toolbar buttons or keyboard shortcuts.A macro is program code preserve automatically or written in a scripting language to improve access to existing commands or to create new ones. signal software Bespoke software (custom-written) is software specially written to admit the needs of a particular customer.

Off-the-shelf software’s advantages t is at a time available it is usually much cheaper to buy it may have many powerful features developed  everyplace many years if it belongs to a suite, it is likely to be able to exchange data and files easily w ith other programs in the suite it is well tested by previous users there is support available from go through trainers and user groups Off-the-shelf software’s disadvantages it may be overly complex and difficult to learn it may be a compromise in the midst of the requirements of different types of users an organisation may be obligate to adapt its business procedures to the software errors may not be fixed rapidly Cambridge IGCSE Computer Studies © Cambridge University Press 2011 Revision notes: 1 Generic application software 3\r\n'
