This compiler error will occur if the first non-blank character after an in (membership) operator is not a '[' (set operator).

For example:

if n_TokenWeekday in (6,7) // should be [6,7]
   // do something if it's the weekend
endif

This error is usually due to the use of parentheses () rather than square braces [].
