Okay, Borislav, your code was what led me to do this correctly. I only added some double quotes; it didn't like single quotes. The reason for the double quotes was chiefly to handle the long windows file names.

Thank you very much!!!

Here is the code that finally worked based on your suggestion:

This code was inside a SCAN. This is the final code. Notice that the Double Quotes are surrounded by single quotes.

lcParam1=oApp.cImageFolder + "\" + Photos.cFileName
lcParam2=lcPath2PICSFolder
lcParam3=lcImageName
lcCommand=[RUN C:\Dev\GetData\ProcImages.EXE ] + ;
   + '"' + lcParam1 + '"' + [ ] + ;
   + '"' + lcParam2 + '"' + [ ] + ;
   + '"' + lcParam3 + '"'
&lcCommand

Your code, Borislav.

lcParam1=oApp.cImageFolder + "\" + Photos.cFileName
lcParam2=lcPath2PICSFolder
lcParam3=lcImageName
lcCommand = [RUN C:\Dev\ProcessImage\ProcImages.EXE ]+ ;
   lcParam1+[, ]+lcParam2+[, ]+lcParam3
&lcCommand
