<h1>Tanks Procedure Reference</h1>
|
|
|
|
<p>
|
|
Each tank's program is run once per turn. The data and command
|
|
stacks are reset at the beginning of each turn, but memory is not,
|
|
so you can carry data over in memory registers if you want. See
|
|
the <a href="forf.html">Forf manual</a> for more information about
|
|
the base language.
|
|
</p>
|
|
|
|
<p>
|
|
For tank specifications (sensor range, maximum speeds, etc.), see
|
|
the <a href="intro.html">introduction</a>.
|
|
</p>
|
|
|
|
|
|
<h2>Limits</h2>
|
|
|
|
<p>
|
|
Forf Tanks has a data stack size of 200, and a command stack size
|
|
of 500. This means your program cannot have more than 200 data
|
|
items, or 500 instructions, including 2 instructions for each
|
|
substack.
|
|
</p>
|
|
|
|
<p>
|
|
Forf Tanks provides 10 memory registers (0-9) which persist across
|
|
invocations of your tank's program.
|
|
