Using Global Macro in another do-file

[Paul Shlapa]

Dear Stata Experts,

I have a global macro g2 in program1, it looks like that:

. di "${g2}"
function y = 80.98921259870659 + -.008561077824043*x + 5.62491844330e-07*x^2

I would like to use it in program2, which is another dataset opened with another do-file. When I type the same command to show me the macro i get nothing:

. di "${g2}"

Both dta-files are being open. I also tried to first run program1 and only after that program2, nothing works.
Why?

Another question: is it possible to use global macro g2 in program2, once program1 is closed?

Sincerely,

Pavlo

That should work in the way that you wish. A global macro should be visible anywhere once it has been defined. That is the point (and the problem...).

The {} are redundant but should not be problematic.
