Assuming your DOS program supports I/O redirection (have you tried it from a command prompt?); to get I/O redirection when running a command line .EXE using WinExec() or CreateProcess(), you actually need to start an instance of the command processor and have it run the .EXE.
So you'd pass a command string to the API call something like: 'drive:\path\CMD.EXE /c yourdosapp.exe parameters < input.file > output.file' The /c parameter tells CMD.EXE to run the command and then exit. Note that you can get the actual name of the command processor by checking the COMSPEC= environment variable, some folks do use others besides CMD.EXE (though it should still be present). Any self respecting console mode command processor running in a Windows environment should support the syntax for redirection as shown.

When running, it gives a prompt and stops. 1. I could execute it as a batch job and pipe the input and output, if I can figure out how to do that in old DOS command language. 2. But that would mean loading the *.exe for each call, executing it, managing the interface pipes and process contexts; Isn't there a way I can put it into my D7 source program as a resource of some kind, or load it once and link it up that way somehow? If it would only load once, when the program starts. Each time the *.exe runs, it could make a copy of itself to run and destroy the answer when completed.
