Amazing debating technique!  The crowd is bursting into applause!!!

Duh!  Really?  From the ANS standard.

6.1.1700 IF CORE
Interpretation: Interpretation semantics for this word are undefined.

Compilation: ( C: -- orig )
Put the location of a new unresolved forward reference orig onto the 
control flow stack. Append the run-time semantics given below to the 
current definition. The semantics are incomplete until orig is resolved, 
e.g., by THEN or ELSE.


I'm so tired of all the petty BS that gets posted here.  Between Gavino 
posting his childish demands, Rod arguing for the sake of arguing and WJ 
posting what seem to be obsessive rants, I think WJ is the least 
objectionable.

Much of what gets posted in this group is of no real interest to me, but 
at least it is relevant to Forth.  This nonsense is just ego boosting 
and compulsive argument.

Not that I expect anything I say to make a difference.  I'm not a social 
worker and I am not trained in dealing with the mental problems 
exhibited here.

 From the ANS standard.

"Forth syntax is extensible; for example, new control-flow words can be 
defined in terms of existing ones."

Do you *have* a point?
