Hi,

yes, if I'm not mistaken this tutorial dealt with the old syntax.

But why don't you check out a tutorial that is more up-to-date? For example, you could look at the C-Script workshop from the download page. This is far better than this old "Programming in 6 Days" thingy! ;-)

Converting wdl into c-script offers only small didactic value.
Well, but if you are really serious about converting it, you can look up the list of old instructions in the manual: Errors & Troubleshooting > Old Syntax.
