Hi,

I entered:

\starttabulate[||||] 
    \NC test \VL test \VL test \VL\NR 
    \VL test \NC test \VL test \VL\NR 
    \VL test \VL test \NC test \VL\NR 
    \VL test \VL test \VL test \NC\NR 
\stoptabulate

And got this error:

! Undefined control sequence.
\tabulatecontent ->\NC test \VL 

Can someone help me with this?
