I have a string that I would like to remove a piece of. I know the Mid function will extract a section out of a string, but I want to do the opposite. I'd like to remove part of a string and keep the rest. Is there a function that does this?

Example:
string="aaabbbcccdddeee"
and I want to remove "bbb"
and end up with:
string="aaacccdddeee"

Or does this have to be done manually using Len, InStr, etc?
