All,
I have a dataset that is weighted. The "weight calculation" has been made
into a variable. How do I use this variable in a regression model? That is,
both OLS and LOGIT? Do I just add the variable to the model(s) or include in
the syntax after the comma?

Look up -help weight-.  The exact command depends on the nature of your 
weights.  The most common are probably fweights (frequency weights) and 
pweights (sampling weights).  If you also have things like clustering 
and/or stratification you may want to look at the help for -svy-.  The 
Users Guide has some good discussions of weights if you have a copy of it.
