Here you can discuss all things Ancient Greek. Use this board to ask questions about grammar, discuss learning strategies, get help with a difficult passage of Greek, and more.
In English, I know it is fairly common to say things like:
If the postman comes on time, you should give him this.
If you don't come back within three days, I'm afraid everyone you love must be killed!
If you start throwing up, you must call the doctor!
I know that if the last parts of each sentence were taken as their own sentences, Ancient Greek would generally use imperatives instead of must and should. However within the conditional clauses, I am not too sure.
The main clause (aka apodosis) is the same regardless of whether or not there's an if-clause. So ean + (aor.) subj. in the if-clause, and dos autw touto or dei (se) dounai ... in the main clause. Similarly for the others.

I think it's very common to have an imperative in the second half (apodosis) of a conditional sentence.
ει υιος ει του θεου, ειπε ινα οι λιθοι ουτιο αρτοι γενωνται. Greek New Testament, Matthew 4:3.
If you are the son of god, tell these stones to be bread.
In your 2nd example, I think the "I'm afraid" would normally be "I will be afraid." In that case, the future indicative would work just fine in Greek.
In your 3rd example, you could use an imperative. δει σε καλεῖν... would work, too.
What does NOT work, I'm pretty sure, is to put that second half into subjunctive. I'd like to hear from someone on that. You wouldn't say the following, would you?
εἰ συ αρξεις ἀποπτύειν, συ καλέσῃς τὸν ἰατρόν.
if you start to vomit, you call (subj aor) the doctor.
This is a point I get confused on because a 2nd language I know (a Bantu one) has a subjunctive that is Greek-like in many ways, but I think in this it is different. In Greek we can only have hortatory in the first person or a sort of "ου μη hortatory" in the 2nd or 3rd person. But you cannot just say καλέσῃς and mean "you should call," can you?
