Yes, you can do this.

A canonical exchange within the do file is

di "Enter value for foo: " _request(foo)

after which local foo contains the value typed.

Just a technical clarification:  it's returned in a global macro and not a
local macro.  (I *have* happened to have used it on rare occasion, and have
got stung nearly each time for forgetting this.)

. display in smcl as input "Enter value for foo: " _request(foo)
Enter value for foo: . Bar

. display in smcl as text "local " as result "`foo'"
local

. display in smcl as text "global " as result "$foo"
global Bar

. exit

end of do-file
