spaces in code

[ssmith]

I have noticed sql statements with spaces in the v$sqlarea, e.g.
SELECT * FROM EVENTS WHERE EVENTS_PROCESSED IS NULL ORDER BY EVENTS_ID
SELECT * FROM DISPLAY_GROUP_NEW WHERE GROUP_ID = :b1 ORDER BY GROUP_SEQ

I know a developer will use spaces in his procedures/packages so the code 'looks nice'. Should he be using tabs or CR instead? Does this take up extra space in the buffer cache? Thanks.

(I presume that multiple spaces were stripped out of your post - use "code" tag = # in future).
The cost of that extra memory must be negligible compared to the value of readable, maintainable code.

(I had a tutor who called this kind of attention to detail "buggering flies"!)
