You knwo what, I think you are right. I will try the following since the program doesnt' take commas between parameters.

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