Ingo,

using brackets will help to solve your issue

global test "Just a "

di "${test}test!"

Using brackets enable you to tell Stata were the global macro's name
ends since a global macro's content is access by just adding the
$-sign at the beginning of its name.

Regards
Sebastian

Dear all,

I have a problem using global macros:

. local Test "aut"
. sysuse `Test'o , clear

works fine and opens the auto.dta dataset. However,

. global Test "aut"
. sysuse $Testo , clear

gives the following error message:

invalid file specification
r(198);

I know that I could solve the problem at hand by introducing a local
macro as follows:

. global Test "aut"
. local Test "$Test"
. sysuse `Test'o , clear

Unfortunately, however, this is quite cumbersome and there are lots of
macros in my do-files which all begin with the same first part (in the
example above: "aut") but whose second part changes (the "o" in
"auto"). I need to use global macros because I have to exchange
information between several do-files and therefore cannot rely on
local macros.

Any help would be appreciated.

Best,
Ingo
