the order of the statements in the config are as follows, as per the show commands (they are in a different order than how they were entered - I cannot see any reason why they were added in this order):
SPARE6509#sho access-list 50
Standard IP access list 50
30 permit 18.104.22.168
40 permit 22.214.171.124
10 permit 126.96.36.199
20 permit 188.8.131.52
50 permit 184.108.40.206
60 deny any log
70 permit 220.127.116.11, wildcard bits 0.0.0.255

This is a Catalyst 6509 w/Sup32, with IOS 12.2(18)SXF6.
Can anyone confirm how the lines of a standard ACL are added to the config?
I agree that the sequence numbers match the order of how the commands were entered.
However, is there any logic as to how the ACL is actually constructed?
As you can see from my original output, the sequence numbers do not follow what is displayed with "show run" or "show access-list 50" (which is the order in which the ACL statemnts are actually matched).
My issue is that it is difficult to determine the actual running order of ACL statements, as it appears to differ from how they were entered.
If I add new statements, how do I know where they will actually be placed in the ACL?
