I think I want to do a logistic regression model, but I'm not sure.

I have a dichotomous outcome with 10 independent variables, some are continuous, some are categorical.

Which procedure do I use to look at the relationship between the outcome variable and each one of the independent variables?

Which procedure do I use to look at the relationship between my outcome variable and the significant independent variables in model building?

How do I know which independent variables to test interactions for?

Thanks for any help you can offer!

That would seem to indicate a logistic regression

PROC LOGISTIC is the easiest one to learn

PROC LOGISTIC DATA = MYDATA;
MODEL DEPVAR = IV1;
RUN;

and repeat for the others.

again PROC LOGISTIC but you don't want to do bivariate screening.
