using * in a for-loop

[Marta Baltruszewicz]

Hello,

I can't figure out what does * mean in front of a for-loop. Here you can see an example:

foreach var of varlist * {
label variable `var' "`=`var'[2]'"
rename `var' `=`var'[1]'
}
drop in 1/2
destring *, replace
d
list

In this example, what does the * put before the curly brackets do for the for loop?
Sorry if it is too easy to answer, I looked through documentation and web but I can't find the answer and it frustrates me, so I'd be very happy for any even one-liner answer

Cheers
