You can see how -indeplist- gets at the names of independent variables
by typing in Stata -viewsource indeplist.ado-.

The basic trick is that Stata will store the estimates in a matrix
e(b) and the columnnames of this matrix are the independent variables.
You can recover those names with extended macro functions (type -help
macro- and click on the link to extended macro functions).
Complications occur when your estimation command consists of multiple
equations (which is not the case with -probit-) or with time-series
operators and factor variables.

Hope this helps,
