Hi Peter

I guess you're after the FUNTION without RETURN behavior, aren't you? I 
currently use Logitech 3.40. This compiler does not issue any error message 
during compiler run. I don't even get a runtime error. It simply hangs the 
system sometimes.

In one of my commerically sold libraries I forgot to place a return statement, 
and it neverthless works until now. Strange, strange ...

I would like the compiler to report the missing RETURN statement. Although the 
compiler normally doesn't know if the ERTURN is ever called. My wish would be: 
The compiler should analyze the program flow to recognize a program branch 
that doens't have a RETURN statement. This case should cause an error message.
