The development of the softwarepackage Vigilant© is started with Clipper '87 and has been futher developed with version 5.x. At last the package has been transfered to xBase first as a DOS application but fast after that it has been made completely grafic. With that it is a full Windows program.
Programs developed with Clipper are mostly not grafic and very DOS oriented. With xBase it is possible to both make it grafic as to use it as a full Windows programm. Even without many adjustments it is already possible to transfer it with xBase to a Windows programm.
By doing this the old programs can be use for many more years.
Inform for the possibilities.
