VatCalc5tb , a simple program which calculates the Vat to add to a price , or the Vat content of an existing ( Vat inclusive ) price . To install Vatcalc5tb simply double click on the SIS file , or copy the SIS file to your Psion and use the Add/Remove command in the control panel to add the program . Start Vatcalc5tb from the Extras bar , You will be asked to select a conversion the options are Plus Vat , Minus Vat , Exit ( and when not run on a Revo , Set Rate ) . If being used on a Revo and the Vat rate is increased , you can set the new rate to use by pressing Ctrl+R . Otherwise operation is fairly obvious in use , enter the appropriate price in the relevant place , press enter and the results will be displayed . Note that the 'Exit' button and command ( Ctrl+E ) will NOT work if any dialog is being displayed . Vatcalc5tb is freeware , I use it on my Revo reglarly and I have not suffered from any unusual growths, injuries or data loss as a result . I cannot promise that you won't either .
