Sadly, ALGOL-M's FOR statement does not allow a negative value
for STEP, so in order to count down we either have to use a WHILE loop if we wish to count down.
or move the subtraction into the body of the FOR loop

integer i;
 
write("First approach :");
i := 10;
while (i >= 0) do
begin
writeon(i);
i := i - 1;
end;
 
write("Second approach:");
for i := 0 step 1 until 10 do
writeon(10-i);
 
end

You can use a for in loop to count downward. You cannot use a for of loop for this.

writeln .i
