Yes, I want my program to remove the last variable in the list, which
can take any name, not necessarily "var20". My problem was solved by
using extended functions like the ones you two suggested.
Thanks Dimitriy and Nick for the help!

An alternative is
local covars : subinstr local covars "var20" ""
but this doesn't work word-wise and might catch
text you don't want it to catch before the occurrence
of "var20". (I have in mind that your real problem
may be with variable names other than those you
give in the example.)
local purge var20
local covars : list revcovs - purge
is probably better.
