[TF] Rand()

[james at zephyr-works.c. (J. West)]

Yes, but this is just an example function.  What I really wanted to do was
something like this:

/def ran_move = /let rannum=$[rand(1,8)]%;/echo %{rannum}%;/if (%{rannum} ==
1) north%;/elseif (%{rannum} == 2) south%; \
               /elseif (%{rannum} == 3) east%;/elseif (%{rannum} == 4)
south%;/elseif (%{rannum} == 5) northwest%; \
              /elseif (%{rannum} == 6) northeast%;/elseif (%{rannum} == 7)
southwest%;/elseif (%{rannum} == 8) southeast%; \
             /endif%;/set norats=0%;

Which of course is a random movement generator, I have another trigger set
up to rerun it if there is no exit in a certain
direction.

Ofcourse,

  /def getrandom = /result rand(0,9)

Might be a little easier.
