st: program to generate variable list as input for other program

[Bob <frotty22@yahoo.com>]

Hi,

I am new to Stata and I want to programmatically generate a list of variable names in a program which I want to hand over to another program as parameters. Unfortunately, if I hand the returned macro over as a string, Stata says " invalid name" and if I don't do that, then the list of variables is converted to values which is also unwanted.

Here is some example code:

gen a1=0
gen a2=1
program define test, rclass
	local s "a1 a2"
	return local mvl "`s'"
end

program define test2
	syntax varlist(min=0 max=100)
	di `0' `1'
end

test
test2 r(mvl)
test2 `r(mvl)'
test2 "`r(mvl)'"

Thanks a lot for your help!

Bob
