Re: st: Is there a way to tell if a local macro contains a particular value

Thanks!

I never realized that the extended macro functions could be used without 
directly assigning their output to a macro. Interesting...

Yes. See -help macrolists-.

. sysuse auto
(1978 Automobile Data)

. unab m_all : m*

. local make "make"

. local in : list make in m_all

. di  `: list make in m_all'
1

. mac li
<other stuff>
_in:            1
_make:          make
_m_all:         make mpg

In your case

foreach v of var var1-var6 {
        if `: list v in myvars'  di "`v' is in the list"
        else di "`v' is not"
}
