RE: st: Command accepts only global macros

This is 100 % true (that "there does not seem to be a problem with -mvdcmp- picking up the contents of a local macro"), and the problem I was facing yesterday was 100 % not logical. And today I replaced all the global macros back to local for a portion of my do-file, and it works fine. So I don't know what went on yesterday since I haven't touched anything. I don't keep a log on that dofile (just store the outputs), so I cannot check whether the problem was specific to some other portion of that dofile. Will keep a log from now on, even if it will be 100 km long. But nevertheless, this problem I was having must have been to do with some faux pas in terms of logic, since that is the only possible explanation. No matter how "real" this problem seemed.

Let us rest this case.

You neither say where -mvdcmp- is from and what version you use, nor
do you show what exactly went wrong (e.g., by showing what exactly you
did).

Assuming -mvdcmp- from SJ, version 10 from 2010/09/17 (run in Stata
11.2), there does not seem to be a problem with -mvdcmp- picking up
the contents of a local macro:

*------------------------------------
sysuse auto, clear

mvdcmp foreign: reg price mpg

loc vlist="price mpg"
mvdcmp foreign: reg `vlist'
*------------------------------------

But with this user-written command "mvdcmp" I am using (a decomposition) I can only define the dependent variable, indep variables and the estimation command using global macros.
