Dear rstralberg,
I have added the new line leading the script to look for mtlFX.c, which did locate in E:\GStudio7\code\ directory. However, the program could not find the file. It generated an error saying "include 'mtlFX.c' not found", either running through SED or WED. I have no idea of what is going on.
I appreciate that you could give me some helps. You are really kind.
Cheers.
