Hi,


Thanks all for your suggestions..

And thanks very much Joseph for that clarification. But,  Does that depend
anyway on whether you use _request(foo) or _request(_ foo)

See below, 

1. with _request(foo)

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

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

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

. 
end of do-file

2. with _request(_foo)

. do "C:\DOCUME~1\corpfin\LOCALS~1\Temp\STD00000000.tmp"

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

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

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


thanks very much
rajesh

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
