Title: Messages

New		Line
1	+	Free Pascal allows the programmer to define normal messages, warning and error messages. These messages are displayed in the message window.
2	+
3	+	These self-defined messages are intended to enable the programmer to better oversee and manage his code.
4	+
5	+	The compiler treats these messages as if they were messages generated by the compiler. This means that if the compiler has been instructed not to issue warnings, then self-defined warnings will not be issued.
6	+
7	+	In contrast, error messages are always displayed. The compiler stops when there are 50 error messages. If an error message occurs, no executable file is created. In the event of a fatal error, the compiler stops immediately.
8	+
9	+	The syntax for messages looks like this:
10	+
11	+	``` pascal
12	+
13	+	{$Message Message text}
14	+	// or
15	+	{$Info Message text}
16	+	```
17	+
18	+	The syntax for notes looks like this:
19	+
20	+	``` pascal
21	+	{$Note Message text}
22	+	```
23	+
24	+	The syntax for warnings looks like this:
25	+
26	+	``` pascal
27	+
28	+	{$Warning Warning Message text}
29	+	```
30	+
31	+	The syntax for hints looks like this:
32	+
33	+	``` pascal
34	+
35	+	{$Hint Warning Message text}
36	+	```
37	+
38	+	The syntax for error messages looks like this:
39	+
40	+	``` pascal
41	+
42	+	{$Error Error Message text}
43	+	```
44	+
45	+	The syntax for fatal error messages looks like this:
46	+
47	+	``` pascal
48	+	{$Fatal Error Message text}
49	+	// or
50	+	{$Stop Error Message text}
51	+	```
52	+
53	+	Note: You cannot use } in a message because this is the terminating character of a message for the compiler.
