I am novice, and I am working now in a proyect with the vga colour palette, over DOS with borland c 3.1.
The project include cpp.h and asm files. Sintactically I checked that is ok, BUT when I do the link tell me DECLARATION SYNTAX ERROR , in the first clase declared in the first h file in the project, I changed the place of the file but still continue give me the same error.
I send here one of the h files in which you can see that it is ok.

// screen to be defined which trigger calls to user-defined
// functions when the left mouse button is pressed and the
// cursor is within the defined region.
