Use global macro to call do-file not error

[Craig Yang]

Dear All,

I'm trying to use the following code to set up global macro and then call do file based on the macro:

global dataset "passenger"
            if $dataset == "passenger" {
                 do "${indexfolder}/Passenger_code.do"  
             }

However, I got the error:

passenger not found

Couldn't figure out why, could anyone please help?

Any help will be appreciated!

Many thanks,
Craig

. global dataset  "passenger"              

. mac list dataset
dataset:        passenger

The quotes surround passenger are not assigned to the global macro, so $dataset evaluates to passenger (without quotes), and Stata looks for the variable passenger, which it doesn't find. There are two things you can do:

. global dataset ""passenger"" 

. mac list dataset
dataset:        "passenger"

Or

global dataset  "passenger"
if "$dataset" == "passenger" {
     do "${indexfolder}/Passenger_code.do"  
 }
