Making a vector

The simplest way to make a vector is with an assignment to a range. For example, `X = [1:5]`, makes a vector named `X` with elements `{1,2,3,4,5}`.

A vector can also be made with an assignment to a list. For example, `X = [1;23;-3;5;10]`, where the elements of a list are separated by semicolons.

The `GENERATE` command also makes a vector, e.g.,

command | resultant vector `X`
`GENERATE X 0,1,,4` | `4` elements: `{0,1,2,3}`
`GENERATE X 0,1,4` | `5` elements: `{0,1,2,3,4}`
`GENERATE X 0,,4,9` | `9` elements `{0,.5,1,1.5,2,2.5,3,3.5,4}`
`GENERATE/RANDOM X 0,5,10` | `10` random elements with values between `0` and `5`.
