Program Syntax
Trigraph Sequences
The compiler accepts three character sequences instead of some special
characters not available on all keyboards as follows:
Sequence
??=
??(
??/
??)
??'
??<
??!
??>
??-
Same as
#
[
]
^
{

}

Multiple Project Files
When there are multiple files in a project they can all be included using the
#include in the main file or the sub-files to use the automatic linker included in the
compiler. All the header files, standard libraries and driver files can be included
using this method to automatically link them.
For example: if you have main.c, x.c, x.h, y.c,y.h and z.c and z.h files in your
project, you can say in:
#include <device header file>
#include<x.c>
#include<y.c>
main.c
x.c
y.c
z.c
#include <z.c>
#include <x.h>
#include <y.h>
#include <z.h>
In this example there are 8 files and one compilation unit. Main.c is the only file compiled.
Note that the #module directive can be used in any include file to limit the visibility of the symbol
in that file.
To separately compile your files see the section "multiple compilation units".
