I'd be glad to write about Forth. When you ask for a comparison, though, do you mean something more like a precis, or a summary? I couldn't compare Forth to...
Hi, I think this is a great idea! Do you want each section to be 'free standing', or discuss differences with other concatenative languages?...

Hi, I'm a Joy newbie, implementing Joy in Visual Basic .NET, but I'm confused about linrec. The help for it says: [P] [T] [R1] [R2] Executes P. If that yields...

Since there are different ways of doing the conditional in concatenative languages, it might be good if we all had them for comparison. This is more or less...
Billy, you will have seen the previous posting about conditionals in Joy. The corresponding one for Forth would be something like this (pardon my Forth, you...

Manfred, I think it would be nice if each section of the comparison could assume basic concepts from the prevoius. Then, ideas could be introduced in this...
