Scott Merryman suggested
drop if substr(automob, -3 ,3) == "car"
and Michael Blasnik suggested
drop if match(automob,"*car")
Yet another approach is
drop if index(automob,"car") == (length(var1) - 2)
which is less direct than the other two. However,
in general, with string tasks, there are commonly
different ways to do it, and the basic string
functions documented at -whelp strfun- usually suffice.
(I found that -help string- pointed me directly
to -strfun-.)
