Digestive Enzymes or HCL for poor digestion?

I know I need to do something about my digestion, but I guess I SHOULD have taken chemistry....sigh....anyhow, anyone care to explain which is better, if I could use both, which would help with digestion most? I'm placing an order today, and one person suggested digestive enzyme, one HCL, and I'm not 'clear' enough to know right now which would do me the most good.



Thanks,
pj
