st: Referencing variable labels in a foreach loop

[Ishir Bhan <ishirbhan@gmail.com>]

Is there any way to reference a variable's label, rather than the
variable name, in a foreach loop?

For example, I want to do a Spearman correlation of one variable with
a list of other variables. Then I want to print the name of the
variable with a significant association along with rho and the
p-value.

I can do this like this:

foreach var of varlist totalgrams-sucralosemg {
	quietly spearman alb `var'
	if r(p)<0.05 {
		display "`var'" _column(40) round(r(rho),0.01) _column(50) round(r(p),0.0001)
	}
}

However, this will display the name of the variable, not its label.
Oftentimes, the label is more informative.

Any way to do this?

Thanks.
