THINK Pascal is long, long dead.

It might work in Classic, if you can still run Classic on the new machine.

Someone who likes THINK Pascal will likely not be at all impressed if 
you try to get them using XCode!  THINK Pascal was a very nice, very 
simple, very elegant program that you just hit a key and it compiled 
and ran.

You can install FPC (Free Pascal Compiler) or GPC (GNU Pascal 
Compiler) and there are templates and such for XCode (discussed on 
the MacPascal mailing list).  But it will require a fair amount of 
work to get going and a big re-learning curve to get doing anything. 
There is no console window  or drawing window, or any support like 
that, so if the user is using THINK Pascal and any of those features 
to make simple Pascal programs, it is not going to be fun.
