One way to help in the interpretation of the coefficients in a model like this is to center the continuous covariate, AGE, and then create an interaction term between centered age (CENTAGE) and FEMALE. Our new interaction variable will be called FEM_CENTAGE. In the SAS code below, we center age at 16.5 years, which is the approximate mean of AGE.

Then we create a new variable called "flag". Flag is the string we use to limit the records for inclusion. In this case it is "BACTRIM". Now we create another new variable called "new_drug". New_drug is actually a numeric variable. SAS has a function called INDEX that will return the location number of the first character in the string.

Each new variable is created using an assignment statement, in which the new variable is named on the left hand side of the equals sign, and the function or expression is on the right hand side. These new variables must be created between the data statement and the run statement of a data step to be valid.
