Yes, it looks like a typo and should be [ instead of [[ These square brackets are not part of the syntax, but are just showing that the colon and label2 are optional, so it means you can have either: GotoIf(condition?label1:label2) or: GotoIf(condition?label1) In the latter case, you branch to label1 if the condition is true, and just continue with the next statement if it's false. > Also, the doc shows: > > GotoIf(condition?[label1]:label2) > > Why is label1 in square brackets and label2 isn't? This is saying that label1 is optional. If you only want to branch when the condition is false, you say: GotoIf(condition?:label2) I guess it could easily have been confusing because typically the condition is an expression contained within $[...], where the square brackets ARE part of the syntax!
