Coding Help Starting and Ending with a certain Character

Once I add the "<100,0,0,0,0,0> it no longer accepts the input, and nothing runs.

No surprise there. The code you posted can't possibly work.

Here is a fantastic idea: delete irrelevant post #19 and edit reply #15 to add code tags, and a description of what goes wrong.

At this rate, it will take you a long time to work through this rather simple problem.
