There’s no instruction to skip some code. You need to use IF… ELSE.. (or ELSIF…) ENDIF to execute some code according to conditions.
The language would need to use alphabetic labels (or line numbers like the old basic interpreters) to tag some parts of the code, but neither is supported.
You might use custom indicators as functions that do something according to some parameters then return some data that they have processed, but it’s not that straightforward and they would still require using IF..ENDIF to make a choice.
