00:00:00,800 --> 00:00:01,800
Hello, welcome back.

2
00:00:01,820 --> 00:00:05,750
In this lesson, we're going to talk about three ARTUS macro names.

3
00:00:06,350 --> 00:00:13,910
So in Free Artus, you would have a name such as Port Max DeLay where you would have the prefix written

4
00:00:13,910 --> 00:00:18,440
in lowercase and then you have the rest of the text written in uppercase.

5
00:00:18,920 --> 00:00:23,870
In this case, the name of the actual macro is the uppercase.

6
00:00:24,680 --> 00:00:32,900
Over here, the name of the macro is mux underscore delay and the lowercase prefix tells us where to

7
00:00:32,900 --> 00:00:34,130
locate this macro.

8
00:00:34,430 --> 00:00:38,600
In this case, this macro is located in the portable that each file.

9
00:00:40,220 --> 00:00:42,600
So we have the prefix and the actual macro.

10
00:00:43,160 --> 00:00:45,680
This is the actual prefix and then.

11
00:00:47,270 --> 00:00:53,210
This is so horrible that we have the prefix over here and the macro and this is the actual Macroom,

12
00:00:53,450 --> 00:00:59,300
we just free our souls, just put this here to make it more readable so that we can go to portable that

13
00:00:59,300 --> 00:00:59,680
age.

14
00:00:59,720 --> 00:01:02,990
To read more about this, Macroom, let's see more examples.

15
00:01:04,370 --> 00:01:11,940
We have this microphone entering the critical section is called a name task and a critical section.

16
00:01:11,960 --> 00:01:16,260
This tells us this is located in the task that each fall we have put through.

17
00:01:16,370 --> 00:01:21,880
This tells us this is located in the project desk that each fall has over here.

18
00:01:22,370 --> 00:01:24,100
And the name of the macro is true.

19
00:01:24,140 --> 00:01:26,320
We have config use preemption.

20
00:01:26,840 --> 00:01:34,180
This tells us that this microbus preemption, we can access it in the free artist config to each file

21
00:01:34,520 --> 00:01:43,010
we have e argue for this tells us that we can find this this one in Project Def storage, although this

22
00:01:43,010 --> 00:01:49,130
is an exception, e r is not a sufficient abbreviation for the word project.

23
00:01:49,130 --> 00:01:50,450
Defs, right.

24
00:01:51,450 --> 00:01:57,340
So we would we would have to be familiar with this, this, in a sense, is the language of reactors.

25
00:01:57,710 --> 00:02:02,360
OK, let's see some common macro names that we'll use if we want to see true.

26
00:02:02,370 --> 00:02:03,680
We would see PDE true.

27
00:02:04,530 --> 00:02:07,890
So wherever we see it, we know is just like a boolean value.

28
00:02:07,890 --> 00:02:08,250
True.

29
00:02:08,790 --> 00:02:15,360
False is false, which is zero in the same way we can use PD Pass as well, which stands for True and

30
00:02:15,390 --> 00:02:16,950
Padfield, which is zero.

31
00:02:17,280 --> 00:02:17,680
Right.

32
00:02:18,030 --> 00:02:24,750
So these are just the the names or these are the the features of the free ARTUS language.

33
00:02:25,220 --> 00:02:31,680
OK, so this all the is we have to point this out in the early lessons as we go and write actual code.

34
00:02:31,770 --> 00:02:32,220
This or the.

35
00:02:32,520 --> 00:02:33,320
I'll see you later.

36
00:02:33,330 --> 00:02:34,080
Have a nice day.
