Problem:

Other than in compiler directives within the NetExpress IDE, can the TARGETDIR environment variable for NetExpress 5.0 IDE path concatenation be exported or set?

Resolution:

Yes.  For the sake of convenience, create a new batch file, (e.g., "NetX.bat") and include "set TARGETDIR" and PATH variable statements, then invoke NetExpress at the end of the .bat file.

Place the .bat file in the root of the local C: drive, or any other location within the system path.  Then create a new shortcut for this batch file on the Windows desktop.
