I checked the TInterval page and that is indeed the case.
One thing to note about using TInterval in a program is that it will not display data if there are lines of code after it. Either the command is on the last line of code, or it will not display anything. The way to work around this is to display the lower and upper variables, as that is where TInterval stores the results.
I really like this site, but I think we need to make the message to search for an issue more obvious when someone clicks the create new thread button. I only just noticed it now when I checked to see if there was such a message there.
That being said, I did learned something today. So thanks Myles.
It totally makes sense to ask on the forum if you don't know if a certain command or program exists though.
P.S. Why do you guys put the semicolons at the beginning of each line? Of course you need them on the calculator to see where a new line starts, but that's not an issue here.
