Ok, now let’s move into even more advanced stuff.<\/p>\n

In this tutorial I will talk about conditions and booleans.<\/p>\n

For making conditional statements, we need []. Let’s say you want to run a code only if a cell is ‘true’ (non zero). This one is the easiest!<\/p>\n

[ [-] your code ]<\/code><\/p>\n

“your code” only runs if the initial cell is non zero. After entering the first loop it clears the cell so it won’t repeat ‘your code’ again and again.<\/p>\n

Let’s say you want to run a code if a cell is not true. Our structure is like this<\/p>\n

..ab..
\n..^<\/code><\/p>\n

And here is the code. I put some comments (numbers) into code so hopefully it will be easier to understand.<\/p>\n

1>+< 2[[-]>-<] >[ - your code ]<<\/code><\/p>\n

We need a temporary cell for this stuff. In this example a is the test value and 'your code' will only run if it is 0. b is the temporary cell.<\/p>\n

First (1) it sets b to 1. After that (2) it returns to a and sets be to zero again if a is non zero. In next step (3) it goes back to b and run your code only if b is non zero.<\/p>\n

Basically we are holding !a in another cell. If a is zero, b remains 1 and code will be executed. If a is non-zero, b will be cleared so 'your code' won't run.<\/p>\n

After those simple booleans, on next tutorial, I will talk about == and !=. It is actually quite easy, see ya!<\/p>\n","protected":false},"excerpt":{"rendered":"
