st: How to get parts of XB matrix

Dear statalist,
I run a regression Y=XB+u, with 30 independent variables. I want to
get predicted XB of 15 independent variables among 30 independent
variables.
Here are my questions
1.The coefficient of an independent variable x is stored in _b[x].
Is _b[x] a vector or scalar?
2. Generally, I use "local" to assign X I want in to a local macro
name. And I can easily change X in the local macro name. How can I
utilize this local macro name when I create XB matrix with independent
variables I want?
Thank you!
