In favour of small amount being specified in sequence of instructions (7)
I believe the answer is:
program
'specified in sequence of instructions' is the definition.
I can't tell whether this defines the answer.
'in favour of small amount' is the wordplay.
'in favour of' becomes 'pro' (being pro a particular cause).
'small amount' becomes 'gram' (I've seen this in another clue).
'pro'+'gram'='PROGRAM'
'being' is the link.
Can you help me to learn more?
(Other definitions for program that I've seen before include "Course" , "Code" , "Enabling instructions for computer" , "A series of software instructions to a computer" , "Instructions for PC, say" .)
