>In converting an older application from Foxbase to VFP 5.0 (running under WinNT 4.0 workstation), I have run into a problem with issuing a DOS COPY command (to concatenate multiple text files into one file)using the VFP RUN command. If I select a Command (DOS) prompt from NT and do the COPY command manually from a DOS-window, it works fine. It will not work from either the VFP 5.0 command window using RUN, or programatically. I get the "flashing" black background as the RUN command tries to parse the COPY command out to the DOS window, but something is being encountered that is preventing it from being executed. I have checked to make sure that all path names and permissions/rights have been set properly.

My guess would be you're trying something like

RUN COPY File1.Ext+File2.Ext File3.Ext

To a certain extent, VFP parses the RUN command prior to dispatching it to be RUN. It may be using its own concatenation to simplify it to

RUN COPY File1.ExtFile2.Ext File3.Ext

A simple thing to try would be:

lcCommand = "COPY File1.Ext+File2.Ext File3.Ext"
RUN &lcCommand

If that doesn't work I would look into the API_APPRUN and ShellExecute() classes available here in the Files section.
