(1)
unab varlist : abc*
global varlist "`varlist'"
(2)
ds abc*
global varlist "`r(varlist)'"
Your loop method should work with
(3)
foreach var of varlist abc* {
global varmacro "$varmacro `var'"
}
but the first method above is better.
The second method is better when you need
the options of -ds-.
There may be a better one yet that
I've forgotten at this instant.
