I need to make a linked list on a SCO-UNIX box,  How do I do this?  Source code or links is what I am looking for.  I know how to do this is DOS, but since I don't the 'new' command in unix I don't know how to do it.

Thanks

Given that this is the C Language forum, I will assume for the moment that you are using C, and wish to make linked lists in a C program.
If all that is correct, and if you used ANSI standard mechanisms in your DOS environment (such as malloc or calloc for allocating memory), then there will be no problem with doing that under UNIX (of any stripe).
The 'new' command, in the context of a programming language, is not an attribute of UNIX, but of C++. You can use that of course, but you certainly don't need C++ for either UNIX or linked lists.

Very good points,  however,  would you have some source code showing it?

I don't have any linked list code lying around. I could cobble something together, however, my point is, since you say you can do it in DOS, that's all you need! You already have the source. There is no apparent reason why you DOS environment linked list code won't work under UNIX.
If you are in fact porting it and it is coming up with a problem, perhaps you could post a sample and we'll look at that. Or, if you simply want a sample of code to run a linked list (regardless of operating system) I can work up a simple example of that.

On the example front; http://www.snippets.org contains public domain code for linked lists, and many more things besides. It is very general purpose. It will presumably work very well. It may or may not help with understanding principles.

I'm not quite clear on why you are unhappy with that answer. Your original question was apparently searching for information with respect to the differences between DOS and UNIX.

I still believe the answer is: there isn't any. I offered to attempt to help resolve any porting problems you may have encountered, or provide sample code (even though you say you have linked list code), or a "professional" source.
If you are still in need of information along those lines, I am still willing to provide.
