Copy global to local

[Henry Strawforrd]

How can I copy all elements from a global to a local? This did not work

global cov gender age age2
local cov : copy local `"$cov"'
disp "`cov'"

[Clyde Schechter]

. global cov gender age age2

. local cov $cov

. display `"`cov'"'
gender age age2

[William Lisowski]

The following shows how to accomplish this using the macro copy command, since that guarantees that the macro contents are not interpreted by the Stata command line interpreter.

. global cov gender age age2

. local cov : copy global cov

. disp "`cov'"
gender age age2
