Actually, the original code used two VARs, not typed CONST. One VAR was
initialized and one was not. I think this is a bug and should be fixed.
As Jonas already pointed out:
"var i : longint = 0;" is internally handled using the same code path as
"const i : longint = 0", and typed constants c

If FPC is going to support downto and by, why not also support changing the
control variable when not in {$Mode TP} as well, and just make a note that
If step is wanted, it's easy enough:
For n:=a to b Do
Begin
if n Mod step <> 0 then Continue;

p.s. make that
if (n-a) Mod step <> 0 then Continue;
for cases where a is not a multiple of step.

James,
not every body is using a GHz machine. I am , for example, programming a 80186

AFAIK these is the standard behavior since the first PASCAL versions.
We must not change it. It prevents a lot of side effects, and PASCAL is NOT C
without brackets!
Use while or repeat instead!

What does continue do exactly? Loop back to the beginning of the for loop
right away?
Hi James,
Yes in effect -- it jumps forward to the test at the end of a loop. Very
useful.

Can we stick to the original request, which was why the handling of the two

You can re-assign the loop variable if you are in {$Mode TP} it works perfectly
fine to re-assign the for variable inside the loop, and I use that extensively,
