That sort of surprises me - surely counting down instead of up would spoil
the expected logic of a loop in some cases
Eg a trivial example, getting the first word from a string...
Function getfirstword(aline:string):integer;
Var
i:integer;
For i:=1 to length(aline) do
Begin
if(aline[i]='
.

This is where 'optimisation' comes in it would count down because
'jump zero' is a single instruction but
would only apply this if there was no reference to the loop var ie
var
i: integer
for i:= 0 to 3 do
begin
write('hello')
end;
but don't do
for i:= 0 to 3 do
begin
end;

Maybe.
But I would suggest that if the doco says it's undefined, then you'd be
far safer writing the extra bit of code required to give you complete
safety.

I use Break if something is found, otherwise let it run to the end.
It's very convenient to test i maxvalue at the end to know if a break
occurred or not.
So as long as I don't
No.
Use a repeat or while loop.

You could do something like:
for i := 0 to 100 do if i mod 2 = 0 then
begin
// blah
end

Hi all. Is there
away in Delphi to do a for loop with STEP in it ?
I..e in VB you can
go
for x=1 to 10 step 2
I wonder if there is
a way in delphi too?
I have had a look in
the help, but did not see anything obvious.
Cheers, Jeremy
