>>I´m working with WIN95 as client and with WINDOWS NT 3.51 and Netware 3.11, calling a DOS program(written in Clipper and located in Netware) from within the .app , I have no problem. But when I call the same DOS program using RUN command I get the next message : "Incorrect DOS Version".

Hi Gray :

Thanks for your advice, it was a key , after many tries I found the solution : In Netware, I found the command COMSPEC=W:public\dos\command.com in login script , I changed to COMSPEC=c:\command.com with SYSCON.
