The optional step clause can be omitted if you want to increment by 1 after each run of the statement
list. If you want to increment by 2 or 3, or decrement it by 1 or 2, then you have to use the step clause.
The step expression (–1 in the second example below) must be a constant.
for iCount := 97 to 122
loop
strAlpha := strAlpha + chr$(iCount);
end loop;
for iCount := 10 to 0 step -1
loop
if iCount = 0 then
strMissionControl := "Blast off!";
else
strMissionControl := IntegerToString(iCount, 2);
end if;
end loop;

Note
Use caution when designing loops to ensure that you don’t create an infinite loop. If your program
encounters an infinite loop, only the loop will run; subsequent queued events will not be run.
