\c random outputs a random number from 0 to 32766, inclusive.

If a \c SEED value is provided, it is used to seed the random number

|
generator, and no output will be produced. This can be useful for debugging
|
|
|
|
|
purposes, where it can be desirable to get the same random number sequence

multiple times. If the random number generator is called without first
|
|
|
|
|
seeding it, the current time will be used as the seed.

|
|
|
|
|
|
|
<pre>
|
|
|
|
|
for i in (seq (random) -1 1)
