@typeswitch, scripts are to record speech, and punctuation isn't just pretty decorators. It denotes pauses, changes in tones, and sometimes replacement for words or modifiers (e.g. quotation marks). Consider your own words by themselves:
grammar is about spoken language it s about how words come together to create sentences with meaning punctuation is part of writing not spoken language it s like spelling which is also not grammar & only applies to written language it s a set of conventions for how to record and transmit aspects of the spoken language using symbols it s good to recall that the spoken language comes first & is much older than writing grammar has existed for much longer than punctuation or spelling
