Hi,

I bought the kindle version of the "Elements of Computing" book, and think that it is great.

I am attempting to complete project 01, but am having trouble modifying the .hdl files, my system is as follows:

Mac OS X 10.5.8 (laptop)
running the HardwareSimulator.sh from a terminal window with the bash command

I edited the Not.hdl file with TextWrangler and added information in the PARTS: section.

after saving the edited version of the file, it is no longer executable. I tried to make it executable with the chmod command: "chmod +x Not.hdl"

but it didn't work, and I can't figure out how to make the file executable again. Any help would be greatly appreciated.
