I tried it and I can use the -varlist(x)- option just fine after Probit. I don't want to beat a dead horse, what you are describing was true in Stata7 but was changed in Stata8.

Dear Shqiponj

If you want to compute the marginal effects after probit, you CANNOT chose
for which variables to compute, mfx automatically the marginal effects for
all explanatory variables in the previous estimated model.

For example, the next will compute the marginal effects for school2 school3
school4 (and for any other indepvar that you use), at their means
probit depvar school2 school3 school4
mfx compute

If you want to estimate the marginal effects for values different that their
means, lets say 5 7 10, try:

mfx compute, at (5 7 10)

for additional information try both
help mfx
findit mfx

Hope this helps

Adrian
