Dear Richard,
Many sincere thanks again!
In fact, I believe that derivabbrev : true is a reasonable choice
in several cases of complicated differentiations and differential
equations (ordinary and, mainly, partial) and, therefore,
Wolfgang's short code (just for this particular case) is useful.
I am always grateful to you for your kind help and support.
Best regards,
Nikos
