Hang on! Programme’s approaching finale (6)

Ross

I believe the answer is:

append

'hang on' is the definition.
('append' can be a synonym of 'hang on')

'programme's approaching finale' is the wordplay.
'programme' becomes 'app'.
'approaching' means one lot of letters go next to another.
'finale' becomes 'end' (I've seen this before).
'app'+'end'='APPEND'

(Other definitions for append that I've seen before include "provided as add-on" , "Add (at the back of a document)" , "Add on at the bottom - say signature" , "Add (to the bottom of a document)" , "Add (to end of text)" .)

I've seen this clue in The Times.
