Correct the compiler's ramble around page (7)
I believe the answer is:
improve
'correct' is the definition.
(thesaurus)
'the compiler's ramble around page' is the wordplay.
'the compiler's' becomes 'im' (I've seen this in other clues).
'ramble' becomes 'rove' ('rove' can be a synonym of 'ramble'**).
'around' is an insertion indicator.
'page' becomes 'p'.
'im'+'rove'='imrove'
'imrove' going around 'p' is 'IMPROVE'.
(Other definitions for improve that I've seen before include "Train" , "Change for the better" , "Ameliorate" , "Make progress" , "pick up" .)
