1. Write your own program based on -foreach-. 

2. -makematrix- from SSC. Here is a semi-stupid example: 

. sysuse auto 

. makematrix , from(r(t) r(p)) format(%6.2f %5.3f)  list  sep(10) : 
	ttest price-gear, by(foreign)  

  +------------------------------+
  |                    t       p |
  |------------------------------|
  | price           0.14   0.887 |
  | mpg            -4.17   0.000 |
  | rep78          -6.02   0.000 |
  | headroom        2.91   0.005 |
  | trunk           3.63   0.001 |
  | weight          6.93   0.000 |
  | length          6.32   0.000 |
  | turn            7.53   0.000 |
  | displacement    6.79   0.000 |
  | gear_ratio     -8.66   0.000 |
