Thanks, Jonas! I think that is what Edward needs. BTW, the latest 
version is at

http://www.ragnemalm.se/lightweight

It is much harder to upload to SourceForge, so I can't always do that.

Then I must guess that you either have problems with the paths (strange 
characters that mess up the command lines) or something is not installed 
properly. What does the "about" box look like? It should tell what 
compilers are installed.

I took that code, created a new document in LWP, saved as "HW.pas", 
fixed the "print" line
to WriteLn('hello');, hit cmd-R. It runs just fine.

.p, .pas, .P, .PAS, .dpr should all work in recent versions.

Let me ask:

- Is Free Pascal installed? For the target you use? (If you use an Intel 
Mac, you need to change target to "Intel" unless the PPC compiler is 
installed.)
- Is GCC installed? (Comes with Xcode, I don't know if you can download 
it separately somewhere. AFAIK FPC needs GCC for linking.)

I am sure this can be solved pretty easily. In all my tests, LWP runs 
nicely as long as FPC is installed. I will gladly fix any beginner traps 
you find.
