It's just a set of variable names, like this:
global dates "last_ar_payment next_bill curr_rate_exp strt stop"
The offending loop then does this, in the same do-file:
******* ******* put dates in Stata format
foreach k in ${dates} {
gen `k'=date(substr(`k'_date,1,10),"mdy")
drop `k'_date
rename `k' `k'_date
format `k'_date %d
}
Then in the second do-file I am trying to do this:
foreach k in $dates {
gen `k'_sunday=`k'_date-dow(`k'_date)
drop `k'_date
format `k'_sunday %d
}
But the curly bracket syntax doesn't work anymore. I need to use
$dates like above.
