A programmer's A-Z? (9)

I believe the answer is:

alphasort

I'm a little stuck... Click here to teach me more about this clue!

'a programmer's' is the definition.
I know nothing about this answer so I can't judge whether this works.

'a-z?' is the wordplay.
'a' becomes 'alpha' (the Greek letter A).
'z?' becomes 'sort' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'alpha'+'sort'='ALPHASORT'

Can you help me to learn more?

I've seen this clue in The Guardian.
