More generally, a wide variety of useful values (current time and date,
current memory, various filenames and paths, etc)are accessible as
c-class values. Just as you can see which output from a Stata command
or program is available using -return list-, you can get a list of the
c-class values by typing -creturn list-. You can interactively display
any of those quantities by typing c([valuetype]), as Kelvin showed
below, or you can feed them into do-files or programs by setting a local
macro to them.

Another way:
display c(k)

There is most probably a better way to do it but this is what comes to
mind:
describe
local no_vars = `r(k)'
di "`no_vars'"
Hope this helps.
