How to store a variable's value label into a global macro?

[BICHENG NIU]

Hi stata masters,

I want to store a variable's value label into a macro, and then I use this macro for further programming. But I can not find any command to store them. Here is an example, I use "label list" command to show the value labels of an variable (carClass), how can I store this value label?

Thanks!

Install elabel (from SSC). Here is an example:

. elabel list carClass
carClass:
           1 A
           2 A0
           3 A00
           4 B
           5 C
           6 D
           7 MPV
           8 SUV A
           9 Specialty

. return list

scalars:
                r(min) =  1
                r(max) =  9
           r(hasemiss) =  0
             r(nemiss) =  0
                  r(k) =  9

macros:
               r(name) : "carClass"
             r(values) : "1 2 3 4 5 6 7 8 9"
             r(labels) : ""A" "A0" "A00" "B" "C" "D" "MPV" "SUV A" "Specialty""

daniel klein gave an excellent answer that doesn't do what you asked. In addition, I would never try to put either the name of a value label or (even less) the entire definition of a set of value labels in a global macro.

The functionality detailed at

help macro##macro_fcn

and at

help mf_st_vlexists

is the basis for using and/or manipulating value labels.
