I've updated to A7.05 and have the following codes
in my main.c

PATH "Art\\Texture";
PATH "Art\\weapon";
PATH "Art\\fx";

and in my work folder, I've the following directory
structure :

..\main\Art\Texture
..\main\Art\weapon
..\main\art\fx

When I compile main.c, I got this error message :

Error in 'MAIN' line 1: 'PATH' undeclared identifier

<PATH "Art\\Texture";>

Any ideas?

Do not define paths in the .c file. You need a wdl file for this. Create a .wdl script with the same name as your main .c file and do all PATH or LEVEL or BIND or SAVEDIR definitions there. You can read this up in the manual under script conversion "from Cscript to LiteC".

Thanks. I've read the Mirgration page and already know it.
I'm just read the manual about PATH, some descriptions are
marked with 'A7' and 'LC', and I'm just think that 'PATH'
is also available in A7.05.

Yes it is of course available in A7.05 but it has like in A7.04 to stand in a wdl file. That's it.
