Re: st: syntax error

[Sergiy Radyakin <serjradyakin@gmail.com>]

David,
Nick has answered it already, but I will just rephrase the manual,
gettoken allows at most two names before the column, but you have
specified 3. The square brackets in the syntax diagrams mean that the
content is optional, but this should not be interpreted as the content
can be stretched to become an array.
Best, Sergiy
