To reinforce Martin's points:

1. The word -local- means what it says. Local macros are not visible outside their locale, meaning the program, do file, do-file editor or interactive session in which they are defined. There are ways of circumventing this, which are only occasionally needed, but it is very much the rule.

2. We need to see code to give precise advice. Your word descriptions plus your guesses on what and why don't give enough information to pin down the precise problems you are creating.

First of all, from your description it is not necessarily the case that you
need -local-s at all. If you do, a do-file counts as one session, and all
-local-s are lost upon its termination.

I would suggest you post example data and what you want to achieve, and the
-local- thing will be rendered redundant...

I am using STATA10 on a Windows 64-bit system.
I have looked up past FAQs on macros as well as the STATA user guide, etc. I have also tried my code on a different computer, but get the same result. So I'm posting my question to the Statalist and would be grateful for any light you can shed on this matter.

I am using panel data and creating quarterly dummies for each year (2000-2009). I then create local macros, one for each year, collecting the quarterly dummies by year.

I am finding that STATA does not create more than one local macro if I try to create several inside a do-file. Consequently, when the do-file then tries to execute a regression, based on the local macros created, the regression output shows no results at all for the variables inside the macros which I am calling in the regression.

If I create each macro in the command window, one by one, and then run the regression by typing it out in the command window, I get results for each of the variables included.

Similarly, if I try to see what variables are included in the macro (by using "summarize"), it doesn't work if the macro was one of several created in the do-file, but will work if I created it directly from the command window.

Can you tell me why a macro might not run from inside the do-file? Is there an upper limit to the number of local macros one can create and call at any time?

I can provide log files and my code if it would help.
