search engine spidering technics

[stevelibby]

hi all
i am looking to bring one of my dated sites that used plain old html up to scratch, two years ago i changed it to asp and with much more knowledge of scripting than then i want to make it far easier to manage. Now the site has 2000 pages.
My question is this
If i were to use an include like so:

If a= 1 then
include file=toplevelnav
else
include file=lowerlevelnav
end if

if i were to declare a at the start of the page would an engine read the else staement?
i am asking tis from a developing/seo point of view.

asp is a server side technology, your asp code is not usually revealed in the html output
