Found when writing documentation
Substring requires you put the length. It should be optional. if you omit it, it should go to the end of the string
I talked to Jeff about this, if you omit the start index, it starts at 0 (this is expected)
If you omit the length though, it assumes zero. it should assume the end of the string.

So it does actually allow blank despite showing as required

Task #11037 has been created. This post will be updated when it has been completed.
