Yes. You could even call it "1": .nr 1 100 .LP \n1 and you will see "100". > Second, what happens if a register is not defined with .nr and used > with \n(xx - would it be 0 or would it be an error? It will have value 0 if it has not been defined. Similarly, undefined strings are read as empty strings, and undefined chars are treated as entities with no content: \w\[novalue]XXXX\[novalue] uses the (undefined) character \[novalue] as the delimiter (i.e. where you would usually use "'" as in \w'XXXX'). Hoping this helps!
