Actually, CodeWarrior probably wiped them out 10 years ago. What you'll want to find/supply is a set of Pascal templates for XCode (google) and then train him in XCode usage. XCode is really straight-forward and easy to communicate in person but rather awkward if all you can say is RTFM. For instance you can set up key bindings to match those of his previous compiler and probably adjust the XCode window display behaviors to emulate the old compiler. Those factors can be a huge help. IOW, his expenses are for the training not the product. Philip Aker [log in to unmask]
