Re: General Question — Notation

[Doug Easterbrook]

hi Brian:

we use a lot of notation --  its good stuff.

but just a plug for some of the older command line things -- sometimes its faster.

for example,
Begin Reversible block
  set current list
End reversible block

for each line in list (selected only)

end for


is faster than the notation equivalent -- so we use the above in time sensitive routines.

do list.$first(ktrue) returns #F
while true

   do list.$next(0,ktrue) returns #F
end while



and sometimes its clearer to use non-notation.



but many other times -- notation is probably the best way to go.
