Thank you for suggestion. I tested platimg ok. I prefer not to use ">" qualifier 
for J504 compatibility. It turns out my code had bugs (more precisely 2 bugs) 
that after fixing it run without problem.  On reflection Wirth is correct that 
it is easy to write incorrect program using a language that is not type-safe 
(both c and J).
