That's not the way batch files work. If you want to include something
in a batch file, you make it another batch file and CALL it.
There is no IFDEF in DOS (including Win9x), though there is something
similar in NT/W2K/XP batch language. Assuming that the variables in
question are environment variables, there are ways to manage the
program flow, but they vary depending on the operating system it's
for.
This group is primarily for highlevel, and perhaps assembly, languages
under real DOS. Your question is more properly asked in one of the
batch groups: alt.msdos.batch or alt.msdos.batch.nt, depending on
which operating system you are using.
The IF help ( IF /?) pretty much covers the basics, regardless of the
operating system.
