OK, I moved it back. Please be specific in what you want and how the command should work. One of the first things you do in programming is come up with a flow chart or at least a word version of one. For example,
- start the command
- prompt for options, default to point input.
- If input equals option A, then do X
- prompt for second point
- add line to database
It wouldn't be efficient to allow just any kind of input. It should be limited to what is appropriate.
