I maintain a superstition that if/else executes faster. Besides, with if/else constructs, we can embed arguments that apple to any conditionls reamianing in the list:

lSomething=.t.
if x=1
   * Do something with lsomething
else
lsomething=.f.
if x=2
   do something with lsomething
else
if x=3
   do something2 with lsomething
else
   lsomething=.null.
endif
endif
endif

I did test in DOS xBase once. IF/ELSE executed in half the time of IF/ENDIF!
