Computer programs for waste disposal (8)

I believe the answer is:

software

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

'computer programs' is the definition.
(I've seen this in another clue)

'for waste disposal' is the wordplay.
'for waste' can be anagrammed to 'SOFTWARE'.
But, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for software that I've seen before include "Computer programs and accessories" , "apps?" , "Computer programs, etc" , "Computer stuff" , "programming" .)

I've seen this clue in The Globe and Mail.
