[SR-Users] DROUTING nub question

Hi

maybe this would work. You have a mask like "111111111111" (you choose 
the max length and the content). From the mask you extract as many 
digits as the length of your number with {s.substr,offset,length}, being 
length $(rU{s.len}}. Then you prepend the result to you $rU.

Hope it helps
