Can I still drive the car or will it damage something else until I can fix it?

What is your question?

I've been noticing an exhaust smell coming from the front/middle portion of my vehicle for some time. My check engine light came on and I took it to mechanic. He ran a diagnostic and said I need to replace my catalytic converter. I'm getting it fixed in a couple of weeks. I have to save up. Can I drive the car in the meantime or will I damage it more? I just need to get from A to B temporarily. By the way - best car ever. This is the first major problem I've had.
