Authorise program range (7)
I believe the answer is:
approve
'authorise' is the definition.
(approving is a kind of authorizing)
'program range' is the wordplay.
'program' becomes 'app' (type of computer program).
'range' becomes 'rove' (synonyms).
'app'+'rove'='APPROVE'
(Other definitions for approve that I've seen before include "Sanction, ratify" , "permit" , "OK" , "Think well of; sanction" , "Think highly of - sanction" .)
