DIA/DAGO was developed to be used on the operating system DOS. The first release was in 1987. Later as Microsoft changed the OS to Windows 9x and NT the customer wants to use the new graphic oriented functions in our software too. Therefore we developed the new product DIAdem. Because this was a significant step it was not possible to use DIA/DAGO-Autosequences, -Setups and –Layouts continuously with DIAdem, except the values. Values which are stored with DIA/DAGO can be loaded in DIAdem.
