is there any way to search a file for a string bottom up?

There are ways, but unless your file(s) are so big that you cannot fit them in memory(?), I wouldn't bother because they are horribly inefficient.

Secondly how do i search ABCXXX where xxx could be Jan Feb...... Dec

Use regex.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
