Jakob,

For question 2, you want to use the extended macro function for the value
label, which is easier to show than to describe:

sysuse nlsw88
codebook race
levelsof race, local(levels)
foreach x of local levels {
	display as result "The value for race `x' is `: label (race)
`x''."
	}

The help topic can be found at

. help extended_fcn
